With as bad of condition as this unit is in I would of passed on it because of the fact that this unit will require a lot more work and effort to refurbish than its worth. I had to do this recently when a local antique mall had a late 1920s RCA tabletop radio for sale in their shop for $15 which I thought that was a bargain until I saw the condition of the cabinet and the guts, the cabinet had been water damaged severely to the point that the veneer was peeling off the cabinet and the guts where severely damaged by mice and deteriorated wire insulation among other things which I had not the time nor expertise to deal with so I ended up passing on it. Although if you have more experience in woodworking and speaker repair and have the patience to replace old deteriorated wire then you did fine in saving this unit. But since I've only been working on antique radios for about 10 years as a side hobby and I know nothing about how to repair veneer work on a radio cabinet and I don't have the patience it takes to remove and replace hundreds of feet worth of deteriorated/mice chewed wires in a radio I would never even attempt to restore a radio like this. Just my 2 cents worth. |

The Philco 16 series is a 1935 or '36 model and a very impressive set. A very high performance 11 tube chassis. |

I know for a fact that my 1932 vintage Cathedral radio I have had a damaged speaker that thankfully was still fully intact enough for a simple unbleached coffee filter paper repair but if I wouldn't of been able to of been repaired, I looked to see if another speaker like it could of been sourced just in case, and sure enough it couldn't, because of it being a 1930s Utah speaker and those are rarer than hen's teeth. The Grille Cloth is also missing which if you don't know what it had in there orginally then it can be hard to get the right grille cloth for the unit. The cabinet from what I could see while no veneer is peeling off, the original finish appears to be shot which trying to refinish these old Cathedral radio cabinets can be tricky especially the fancier ones because you have to try and get the finish to go on evenly within all of those little crevices in the moulding without it dripping and even stripping those cabinets can be a pain because of those various crevices in the fancy moulding. Anyways I was just saying that if it were me I would of passed on something that were in that kind of condition because with my expertise level (which is pretty much non-existent when it comes to working on pre-war radios) I wouldn't of bothered with it unless it was known to be an extremely easy radio to service. That's all I was saying, I wasn't implying that it was a bad radio or that the radio wasn't a high end radio or whatever, I was just saying that in my position if I saw a radio like that that had a severely damaged speaker and no grille cloth and unknown condition guts, I wouldn't personally bother with it. Referring back to my experience with seeing a late 1920s RCA Table Radio (Tombstone style) at an antique mall for an extremely good price but then it was because the cabinet was trashed (severe water damage and severe veneer peeling issues with the cabinet alone). Then it looked like the guts had mice living in it several times in its life as the chassis was severely corroded by mice pee and wires were chewed clear through in critical areas including in the IF Cans, and the original cloth cord was pretty much gone and the dial string was broken and the tuning capacitor was seized up (you couldn't turn the tuning capacitor with your hands) which is why I had to pass up on the radio even though it may very well have been an extremely valuable unit once fixed up. But to even restore that unit one would of had to sink more money into the unit than it might of been worth. And the OP was asking for people's opinions on the unit, and so I gave my opinion on it. |

IIRC Philco repair bench had a good table of block cap part numbers with an explanation of their contents (my go-to resource), but I just checked and I can't find it, along with a good portion of their site...What happened to them?

If the speaker is beyond professional help there is always a way to spec a new one (of any vintage including brand new). The most important thing is geometry and diameter. If it is the same mounting size you don't have to modify the cabinet, and there are ways to make it work electrically. Getting the same voice coil impedance is important to reusing the same audio output transformer, but there are ways around that. Speaker impedance matching transformers exist, and one can spec new audio output transformers by knowing/finding the plate impedance of the original and getting one that matches that to the impedance of the new speaker. If the original had a field coil you can use a PM type speaker and substitute the field coil in the power supply circuit with a power resistor or preferably a choke of similar impedance....Sure it is part of the power supply filter circuit, but there is a lot of fudge factor in those designs, and if you've got some spare parts to play with it can be arrived at easily with experimentation. Knowing theory of operation, and associated maths helps the process greatly and helps ensure it will work best the first try. It is good to know your skill level, but challenging yourself, learning new techniques, and approaching things by not assuming things are impossible/impractical will help you grow...Thirst for knowledge helps too. ...That said if you told me you were captinclock back under a new user name, I'd believe you...Your writing style/personality feels rather similar.

CaptainClock mentioned many times that he has Autism, ADD, and ADHD, which with that said it makes it hard for people like that to communicate what they want to say without sounding a little standoffish because that's just the way they are its an issue that he was trying to work on every day and its tough to try and say something (especially on the internet) when you can't see the person's facial expressions to go with what they're saying. So of course if someone said something about an old radio that they thought looked like it was going to be a little tricky to work on but then someone else came along and read what was being said and took that comment as being a mean nasty comment when the comment wasn't meant to be originally because the person couldn't see the facial expression of the person when the comment was initially posted, then of course there's going to be some problems. That being said Levi (aka formerly CaptainClock on here) has had lots of trouble with cyber bullying and trolls on just about every single online forum he's ever been on. The worst one was when he was a part of an art forum called deviantArt for a while and that website which was supposedly supposed to be a "friendly place for aspiring artists to hang out and share their artwork with others", was actually quite the opposite of what they claimed their website was, and he ended up in the end having a young woman and some of her friends on that website try and set him up to look like a pedophile (even though he isn't one) by hacking into his facebook page and computer and posting inappropriate pictures on his facebook page and what not just because he was attenpting to make friends with other fellow forum members so that he could have some people he could ask about his artwork. Now that being said you can kind of understand why he takes offense to comments that people make that sound threatening to him. |

So, are you saying that you are not he who was once named "Captain Clock"?

Personal opinions aside (I was not the one who banned clock and did not mind him when he was not stirring up sh!t) it is against the forum rules to create multiple user accounts, and IIRC against the rules to return under a new user name when permanently banned...This transgression which you seem to be admitting to will likely result in you getting permanently banned again.
A certain well known/liked Michigan member was nearly banned over creating a second comedy account (sanjarali) once. Rules are rules. That said I'm issuing you a one day ban while I discuss whether or not to allow this return with the fellow moderators. If the others don't say "make it permanent" consider yourself lucky and be careful how you post. A certain conduct of discourse is expected here, and regardless of your circumstances if you make too much of a nuisance of yourself anywhere you will eventually get the boot...It is just how life works.

Hundreds of feet of wire in a table radio?...Lol come on, seriously? Those block caps are easy...With the right screw driver I can chip the guts out without heat in under a minute. Most block cap era Philcos I only use the schematic to determine the pin-out of the ant and osc coils*. Just change the lytics, re-stuff the block caps using one of the internet references to determine their contents/pinout and if the ant and osc coils are good the chassis should work. Often the single layer ant and or osc coils are open (2 of 3 60 chassis I've serviced, and 2 of 2 80 chassis were open)...Often the break is near an end so deleting the corroded turn or two and reconnecting the end will fix it, but I've had some where the whole winding was full of opens....Those I just count the turns, remove the old and rewind the same number of turns with Radio Shack phono pickup wire (always works like a charm).

Actually if you count all of the hair thin copper wire in the IF cans in these old radios then yes technically these radios do have hundreds of feet of wire in them, someone on here mentioned that one of the IF cans in one of these radios has as much as 1,000 feet of wire in a single IF Transformer winding and most of these old radios had as many as 5 IF Transformers in them (especially the higher end models). So I'm not really that far off by saying hundreds of feet of wire in an old radio, yes I agree that the interconnect wires on the underside of the radio chassis maybe doesn't amount to 100' (but close though in some of the higher end models) but like I said when you count the wire used in IF coil windings and the power transformer, and the speaker's output transformer and voice coil, then yes the radios easily can have hundreds of feet of wire in them. |

I read, that they were "vacuum impregnated", so they did have a long life, but after 80+ years??? I use my $8.88 Harbor Freight heat gun and heat them a bit and the guts pop right out, with little effort. |
