lets imagine I'm in my 50's riding a competition level X country mountain . bike @ least 75 mi a week in the season and getting some gravity and getting laid regular with my real nice ,smart good looking professional gal Tuesday and maybe Thursday too and current weekend getaway squeeze and feel a little tired around all that thinking my GP may reccomend a vitamin regimen and maybe something else eh?
EDIT :

Well it was a cardiologist and sudden coronary by pass surgery without more than a days delay ,
wholly unexpected by me or my GP or anyone that knew me at all including the gym trainers .

The analogy here is these radios are lethal and you are being dismissive about that and your GFI outlets are not foolproof and neither was my significant exercise regimen .if you can not see the analogy here perhaps have someone explain it to you .


.True story here and ......We never know when the bogey man is coming .

The next day after a cardio ultrasound my suddenly new and spendy cardiologist comes in the room with the results and he says to me :

"Hey bud "you need to have a by pass surgery it's definite you need that "

> I ask him when? > He tells me :


" I want you to check into XXX XXX hospital right away without delay we can call someone for you also let them know where you going and they have long term valet covered parking for things like this there too so your new ride and your phat grips on it out front here will be safe there."

" We let your GP know ,he well be checking in on you when he makes his rounds there and we made all the arrangements , "

"they know what to do when you check in at the lobby and they will put your Rolex in thier safe right there in the lobby or near there until you leave and the knife will be seeing you for a consult before the action gets started no later than a day or so ."

.True story here and ......We never know when the bogey man is coming and mine is statistically long overdue to return .

Good God, all that dialogue over a S120!!!
BTW, I'm a little more than just a hobbyist, plus I have four years of Tech school, associated with my Electrician Apprenticship. Plus, several years of practical experience, that no tech school can offer! Why do you think, I knew exactly what set you were working on, if I didn't have experience with the faults of the set.
Another thing, I've been equipping my workshop with GFCI receptacles, ever since they became available, something like 30 years. It minimizes a shock hazard when working on equipment like this!

Sounds like he went here for his medical work. https://youtu.be/jWMO3rAD98k?t=1m32s

Too bad you have stooped to this level and don't value a good argument but given you may wholly overestimate your abilities here I am not surprised

Consider all this :

1. You may believe you are an above average Millennial .

2. Where are your valid statistical data and test subject data stores or [citations] and or some PhD peer reviews and papers to support your statement .

3 Did you use trained or random test sample groupings for your conclusions,controlled conditions, any accredited test proctors or any clinician or standardized testing ,

4. Did you use a statically valid number of qualified or peer test subjects?

5. Did you use reliable double blind ABX testing like we do in pharma research ,statistical validation,engineering validation ,field product reliability
validation, random MTBF destructive & competitive testing and many disciplines or no ?

6. How did you arrive at your statistically valid conclusion or anecdotal subjective or cognitive bias hypotheses ?

7 . Let's allow an argument of how many of your radios statistically just needed a random tube substation ,some cleaning , new connections ,De Oxit or only obviously visibly bad discrete circuit parts ,just new circuit part hook up wires jusk electronic cables ,a RF or IF coil or related cap again visibly bad parts or tubes ,only a line cord , a pot or switch (s) ,recap instead maybe resistors .lyrics or a loudspeaker.or a comprehensive electronic restore .


7.a Le'ts allow an argument that most ME, EE, ,EE grad EE undergrad deals in statistics ,materials science ,electrical conductivity, circuits ,thermal design, micro circuits ,controls,software and HDWE , diffused silicon , metallic alloys ,refined base metals, elements rr diffused exotic metals......... ,

or fabricated materials ,network controls ,fail safe and and devices and the scientific method , what I missed here you probably can not imagine outside of a lab ,university or private sector tech ,industry ,materials , eng. ,science and silicon .

8 Let's allow an argument that Discrete circuit superhet. AM radios were not rocket sconce since 1939 or perhaps well before that and niether are yours or mine .

7. How is working on 200 or even 2000 collector or refuse radios a credible electronics qualification as with a professional vetran techician resume and concomitant qualifications . or an accredited academic and lab A.A. , EE grad or EE undergrad studies ?

7a. Let's allow an argument this would be absurd if you know better more on that later,

9 . There are those that say some Millinials a have recieved poor educations and were never thought to think critcally or value a good argument like scientific or geo political debates and supporting arguments like technical, engineering ,medical and science necesities .


9a. I raised a now grown Millinial ,extended millennial family & virtually most the friends when I wasn,t abroad or far (work) and lots of them are *or were* lacking desirable educational and employment or skills ,attributes or situational skills we found that in the 105 yr old Fortune 100 global company I retired from managing at also and some of them typically over estimated thier abilities with exceptions ofc.***

9b. ***** This is not unto itself an indictment of Millennials at all there are many ,exceptions but more an indictment of our failing institutions .****


10. Let's allow an argument that without concomitant education ,experience in the private sector or related pubic sector and qualificatins any given enthusiast may be confused about all this and over estimating thier abilities ?????

11. Let's allow an argument you appear to be wong about an AA5/AA6 heater order and Old coot 88 is the smartest one in the room abuot tube radios or more


12. I was there (ONLY part time short timer +_hobby ). I chose a different career and study than TV radio & ultimately no electronics beyond the current hobby and , ahem ....hacking PC 's maybe decades ago just to look but never private citizen except a prank to someone I knew with a restart out for them (from mail attachment , all the geeks did it then ,


Today hobby are Nix & Windows 10 PC PC, solid state ,digital CE repair only if I have to and I can ,digital codecs ,Window 10 software validation and I/O throughput Linear Power supply class A+B amplified devices like amplifiers and 5.1/7.1 AVR and PWM/PSU & complete LCD TV repairing , LCD TV panel LED today but not for$$ I dont need and not public and not frequent like a bench tech )


13. You have to respect the EE's that make all this possible and moreover the real techs today and the old school techs that get it done and blazed the trails and figured out and fixed the many EE's or production boo boos and still do today in the field its not like a hobby at all . My radio her came new with the wrong 50C5 cnrtl grid cap

14. except for the good heater wire order and related heater cathode faults noting it getting all new NOS tubes anyway I have now

I have what we call a null and what I aleady new here all along but din't call the folks on it and dismissive FUD about about the AA 4-5-6 lethal radio hot chassis that can fry someone without much provocation

Nonsense about electromagnet speaker outside of the scope of this thread or 80 years now or about my radio and ( an unqualified opinion ) about my radios thd+n distortion and speaker that is poor one but not to this high thd+n I hear

An opinion without any supporting arguments or direct observations or inquiries about the severity of the audible distortion ,comparable or ,at least the volume setting.

A qualified conclusion or peer reviewed opinion result is called the scientific method where I was educated some folks may not be familiar with , and you missed something about heater wires you were corrected on

15. trus`me I can fix this radio on my own and your LCD TV or PC and more presumably without vacuum tubes ( I can fix some if that and figure out the rest by reading the circuits (reference design) ) and tube data and whatever testing I know how to do

.You ever seen a discrete AM radio with a complex Compactron tube ?

You now what scan line NTSC color TV demodulater (s) do or what they are ? >I worked on TV's with those in a TV shop and way more complex stuff ,some at CAL State ,more abut that later


16. IOW maybe ,Let's allow an argument to your day job instead of advise on these radios or get detail observant here ,presumably you are not an EE engineer or undergrad and who knows what kind of radio tech?

EDIT : 08.15.2017 08.15.2017

17. I never mentioned where or exactly what I studied anyway ,since the subject is tube radio, . most folks don't understand it anyway ,you have to be there or in the business .



17.b LOL.. After High School Grade 10,11,12 Advanced Electronics & Lab
3 hours per day 5 days a week and some vac.,tube study + projects and same for Solid State and ,some computers and and lab inst.+ math drugery for all this ...................,

Our HS instructor for 3 yrs was an E,E, and industry & spared no money funding all this in a new dedicated electronics lab building with frosty cool AC too and the best labs this side of a spendy university .

1967-1790 H.S, those were optimistic and superb upper middle class times for us with obligatory nice vacations amd some weekenders & summer (but coll.. prep drudgery lots' and I worked hard too also ) and America had the Apollo missions

Then there was all this :

18. LOL before my unrelated career subject degree at Cal State my most significant related edu. was Electronics and Solid State Engineering study (~ 3 yrs) at CAL State that was not so much about tube radios and TV or a usually poor for profit tech school diploma mill study to a dead end job like a (** by now**) a vanishing TV shop bench job or fixing office copiers or printers in the field or pulling cables for TV content productions amd pooling CATCV cable and putting yip TV dishes or selling or Geek Squad at Best buy


: 6 Years here TRUMPS a thousand radios tongue:

full stop .

Thank God here at VK we don't pay by the word , cause this dude would have a $10K bill after a week of posting

[init4fun]

PS , NO I most certainly did NOT read the entirety of the post before mine .
Like the old proverb , oftentimes the more words there are , the less is actually being said .......

# That'a a good point I may delete the anecdotal drama rubbish or append it
FWIW that drama was the analogy to a lethal radio and common design here a poster was dismissive about and his GFI outlets or mine are not foolproof, they are not crowbar switches or fast blow fuses or isolation transformers a fool-would not own if they work on a lot of these AC DC tube radios .

They say you cant fix stupid and electricity doesn't care

ppfftttt yes too wordy , see the edit and it should be clear now !

OTOH maybe the original direct reply to another was an analogy with a specific intent over your simple mind anyway

When you resort to hurling personal insults at folks like the one I quoted above , it's proof that you've lost any kind of original point you were trying to make , and are now looking for a good ol fashioned "internet dustup" ....

Let me tell you , this board takes a VERY dim view of such provocation , and I have seen plenty of folks shown the door for hurling just the kinds of "simple mind" insults you just posted .

Think about it ......
