Hi All;
I got some of the Caps on saturaday.. If I don't have to go to work, I will take out the 10K resistor and put it back as per origional, along with changing out the .05 caps..
THANK YOU Marty

Hi All;
I have started to change out the caps..
I have also noticed, that my 630 is an early Version.. On the three terminals on the back, mine has two caps and a resistor, for the Sync modification, where as the 8TS30 has the one Cap in the 1st Video section.. Also on the Sams there is a Tie on point for a couple of Caps that I don't have.. I am not saying that they don't exist, but they are wired somewhere else.. I am also going to check that the compensating cap for the 1st Video and see if it is in the circuit..
THANK YOU Marty

well ive been there and there is alot of those caps so be real careful replacing them, one at a time. i have a 1947 fada that uses the same chassis and i changed every cap except the domino micas, but did replace a verticle mica cap for the timing as well as another i think it was around the 6sn7 tube for the horizontal. and of course the electrolytics. i did place 2 caps in the wrong place at the 6sn7 and ultimately because of probing to find out what i have done as far as a mistake i burned the power transformer out. but i found a nos for 60.00 put it in look for my mistake fixed it and this set today works like new. so dont do what i have done, take your time its worth it in the end.

Hi All;
Timmy, I plan on doing a few caps at a time, then testing it.. Before going to the next group of caps.. Hopefully, It will make finding mistakes alot easier..
THANK YOU Marty

oh just keep in mind that when you clip one and turn for a moment and dont remember what end goes where then its trouble but if you have the sams like i have then it makes it easy if things go wrong and you supect you maybe put something somewhere else by accident. in my case what happened was my daughter was asking me something and this triggered what happened to me with 2 caps being put in the wrong place which had to do with horizontal frequency and a blue glowing hot. this drove me nuts but i looked back on the sams and wow there it was. good luck with the 630

Hi All;
Timmy, Thanks for the warning.. My biggest problem with the Sams is since mine is a copy, and my eyesight isn't that great, I have trouble seeing those little details.. Like where wires go or are attached..
I have an 8TS30, that I use for comparison and the Ryders..
This set didn't have any compensation Cap on the 1st Video Amp, so I took it from the 830.. I am just about to try it for the second time today.. I have 6 (each) .047 Caps done as of now..
Its a little better each time I try it.. Still has smearing issues.. But I can make it lock and unlock , (I think) in both Vertical and Horizontal.. Its possible in the sync sections or still in the video sections.. I have some other Caps on order and they will not be here for a week or so..
THANK YOU Marty

Hi All;
This is the longest that the set has been on !!
I put a Video signal on the connector on the back, part of the Horiz. Sync Discrimiter.. I origionally thought it was part of the Sync Amp.. And I got some picture .. :banana: Its a mess, but it is Video !!!
I need most likely to replace the Sync Integrator Caps and Resistors, when they come in from Mouser.. I will look at the 1st and 2nd Sync Amps and the Sync Seperator and see If there is any other Caps that I have at the present that I can replace now..
THANK YOU Marty

By golly sounds like she's gettin' there. :yes: It might be s good idea, especially when replacing resistors, to power the set up after each replacement. If a resistor happened to be off value by a single decimal place, it can really throw you for a loop if you don't catch it right away.

the sync loc i think has 1 or 2 caps right off that unit. and its not a good idea to touch the adj on the inside of the chassis of the sync loc because there are 2 adj , outside and one inside.

Hi All;
Timmy, I am not even thinking of much in adjustments yet.. Too many other issues, that have to be resolved before I get even close to that point.. Thank You Old Coot, I would have not thought of that being an issue..
THANK YOU Marty

Hi All;
I am now a firm believer in doing a few caps at a time.. I just did a few put it all back together and No Picture.. Took things like picture tube out and turned the chassis over, and after comparing my two sets I found my wiring mistake.. I fixed it and tried the Set again, and I have a Picture Back.. :banana:
And If you have the capability having two similiar sets, Helps alot also.. Doing an A to B comparison, pointed out the mistake real fast.. :thmbsp:
THANK YOU Marty

Hi All;
I have all the Caps in that I currently can replace.. The next batch should come in early next week.. When I can do the rest of them.. At present the picture is kind of folded over.. But, untill I can get the rest done, I can't do any real in depth analysis.. I am glad that I have anything on the screen for now.. I figure some picture is better than No picture..
THANK YOU Marty

I'm looking forward to final pictures of this restoration. Keep up the good work Marty :thmbsp:

Hi All;
I got the Caps in, I didn't expect them till the middle of next week.. :banana: The TV is put away for awhile, and the kitchen Table has the Stepper on it at present.. I can't put both on the Kitchen table.. :D I just Reprinted up an 1" and a quarter of Documents and old emails, that I need to re-read to get back up to speed with it.. I couldn't find the papers from before.. :sigh:
This will give me a small Break from the TV, so when I go back to it.. It will be like all fresh and new and a renewed perspective on it.. Which can make me notice things I didn't see before.. :thmbsp:
I wish those of you that are interested in either the TV or the Stepper, lived closer, so I could explain my thinking in person, while working on something, and we could both be actually looking at it..
THANK YOU Marty

Hi All;
I have brought back the 630 from the Back room, and put the Stepper away for now.. The Kitchen Table has room for only one or the other, but not both..
I have more caps to replace.. And can start testing parts of the 630 once I have replace more of the caps..
THANK YOU Marty

Hi All;
I don't have picture, but I have almost all of the caps replaced.. The only exception is the Audio section, which works fine for now.. I am going to need to do an A B comparison between the 630 and the 830, and see If I have a wrong connection..
THANK YOU Marty

Hi All;
I have the picture sort of back, I can get a Raster that almost looks like there is something there.. Or I can get a raster that is about 1 inch high over and over again on the screen.. It is not rolling in either direction, I can get the signal to lock in.. Not sure what the trouble is yet..
THANK YOU Marty

Hi All;
I have had my 630 on its side and then it has no voltage.. But when it is sitting correctly, it has some voltage, since I get a picture.. When on its side I don't have the picture tube in the set.. I have it upside down now, without the picture tube, and will try to measure the voltages.. Is this because of the tubes being OLD or don't some of them work when laying on their side ?? Or is it my being too old ??
THANK YOU Marty

I find your post a little confusing. Are you saying that the set doesn't turn on when you have it on it's side ?

Hi All;
Bob, sorry about the confusing statement.. When the set is on its side, I get NO high voltage.. But, put it upside down or rightside up and I get High voltage.. With the Set upside down, and my Variac set to 110 volts input, I get on the 5U4 pin 8, and C220A, Field Coil, I get 259 volts, If I up the input voltage to 120 volts, the the reading is 290 volts at pin 8 and the Schematic shows 300 volts at this point.. But, If I put the chassis on its side then the Voltage is 0.. I think it mostly is that my 5U4's along with all of the rest of the Tubes are all old..
THANK YOU Marty

Are the 5U4 filaments lit when you lose voltage?

Clean the pins on your 5U4G rectifier tubes and make sure they are seating firmly in their sockets no matter how you turn the chassis.

Cleaning tube pins and sockets is so important that I always do it BEFORE any recapping.

http://antiqueradio.org/FirstStepsInRestoration.htm

Every tube, new or old, needs to make clean connections inside its socket, or all bets are off.

Hi All;
Old Coot, I just tried the Chassis on its side since the other day and I got filaments and I also have voltage.. The 5U4's and the 6BG6 are all held in by holding rings.. The 6BG6 is out right now, since I don't have a picture tube in the set.. I am not sure what has changed since then, maybe I didn't have as good of a ground connection as I had thought.. It was thru an aligator clip wire..
Phil, I will need to wait awhile before I have the funds for some Deoxit.. and find a place that locally carries it..
I had wanted to test the Video amps, with a video signal from my B&K 1077b and output with my scope.. Since the weak picture suggests that they may not be correct, or that the tubes are not doing their job..
THANK YOU Marty

You won't get HV without the 6BG6 installed.

Hi All;
Bob, That the whole idea.. With no picture tube installed in the set, I don't need the High Voltage lead with 10K banging accidently into my arm, while I am trying to take some readings, either with the scope or with the volt meter.. Since, I am working on other sections besides the High Voltage and the Horizontal sections, I don't need to worry about them at present..
THANK YOU Marty

You stated earlier "When the set is on its side, I get NO high voltage.. But, put it upside down or rightside up and I get High voltage.."

I thought that was the problem you were trying to track down.

The lines below 2kV and above heater voltage are called B+ (and B- in some cases).

Hi All;
Sorry, I used the wrong terminology What I mean't was the B+ and not the Really High voltage.. Now I understand what the confusion was all about.. I was thinking of Voltage higher than Filament voltage, but lower than Picture tube 10K voltage.. I know about using B+, but it completely slipped my mind and thoughts.. Which is also, why I had trouble the other day, most likely I didn't have something connected or turned on and didn't realize it.. And so I thought I had 0 Volts on both my scope and on my meter.. Then later, when I had the set right side up, I did something different.. I have know Idea what it was or is..
THANK YOU Marty

Hi All;
I Think I found out what the problem was.. The plug from the TV (cheater cord) or the Socket on the Variac is intermittent, and so most of the time it will work, but sometime with only slight movement of the Plug from the cheater cord, and I have no connection..
THANK YOU Marty

Deoxit is sold at guitar and music stores. You can also get it online usually for a buck or two less than the in-store price. Google Deoxit.
