1954 Philco high b+ issue.....

[Davala]

First..... I'm so excited to be posting again after many years of.... well... not able to acquire more TV's.... My parents moved to Oregon last summer brining with them my Dads old college TV.. A 1954 Philco 22BU4001. I worked on it years ago as my first electronics restoration when I was in 8th grade(mid 90's) I was featured in Popular Communications... Well I butchered it. When I pulled the chassis just a few months ago I found I removed the silicon diodes replacements out of the power supply. I even stole the replacement electrolytics from the sweep/power supply chassis. Numerous cold solder joints were found, leads falling off... Two resistor leads were connected to the wrong terminal. I found two resistors that should have been in series were actually connected in parallel. I was 13 at the time, and 32 now. I know I should have started practice on a radio, not a 50's TV. Following the schematic I fixed almost all my errors. . rewired the power supply etc..

I'm plagued by a sync issue both vertical and horizontal, and the AGC/gain. I know many will argue about my power supply, but as I threw away the original selenium rectifiers as a kid and also stole the silicon replacements for another project I found two Federal seleniums on ebay.. This set when working properly will be used on a variac at 115 volts, which is what I've been using for my tests...

B+ is 238volts... Schematic is 245(at 117VAC) so I'm not concerned that the selenium rectifiers aren't supplying enough voltage.. Its my 130 volt B+ circuit that's causing my issues.

The 130v B+ is tapped off the 245b+ via a 2.5k 8 or 10 watt power resistor R29. I'm using a 2.6k 10 watt and I'm reading 40 volts high... My 130 is actually 170v. The original power resistor is disconnected but in the chassis. Years ago I just replaced it assuming it was out of tolerance. I measured it and its nearly 4.0k so I assumed Sam's mislabeled the value. I jumpered in the old power resistor to check the 130 volt B+.. The same reading as before.. 40 Volts high.. How is that possible with two very different resistance readings?

I took some voltage readings in the sections that use the 130v B+. the 3 6CB6 IF stages all show the correct plate voltage of 120 and 115, but the screen voltage is 170 where the 130v connects to. The plate and screen voltages are both derived from the "130v" source but pass through the IF cans to the plates.. Why is the plate voltage ok when the screens measure 170? The screen voltages should match plate voltages. Again the 6U8 sync amp, plate voltage is ok, but pin 3 measures 170. Video output tube 12BY7 is the same with the same high screen voltage.

I've checked the wiring of the 130v sections via the schematic and nothing seems miswired. What else should I check? The only thing left in my opinion is to disconnect the 245 volt source from the 130b+ and measure to see if there is 40 volts.. The other thought would be to disconnect one by one the 130 volt sections and see if the voltage drops to normal.

I get sound and video will connected to the digital tuner but the AGC/gain/contrast is overdriven. At min contrast its still excessive.... Sych isn't stable either.. Those sections use the 130v...

I'm a airline pilot and am gone from home for 4 days. I scanned a partial schematic for reference before I left.
The schematic is found in Sams set 227 Folder 10..

Please offer and suggestions.. I've been going at this for a couple months(not every day of course). My wife thinks I'm wasting time.....
