TS18A schematic

[mstaton]

Looking for a copy or original TS18A schematic. I have the Sams but it’s not really close to being right. Set is a 9T1. Thanks

Here's a schematic from the Wallace Telaide.

Thanks Bob. The only issue I see is that my horizontal transformer had 6 wires. I only seem to find ones with 4. Mine is attached to the outside of the chassis

[bandersen]

I have several TS-18A chassis and all have it mounted on the inside with four wires. Could yours be a replacement?

[bandersen]

Scratch that comment. I do have one like you described. https://flic.kr/p/bDAkFZ

That’s the one

If you have a schematic, I’d be happy to pay you for it.

[bandersen]

Nope, not that I can find. I went through Wallace and Riders. Neither has a TS-18A "late" schematic.

Thanks for trying

Will low high voltage (3.5k) affect sync. I tried different (used 1B3’s) some kinda work, some don’t. Still has the original Motorola 1B3. BTW, I ordered some new ones in case

[bandersen]

It might affect vertical sync since the plate voltage for the 6SL7 vertical output tube is derived from the HV supply.

You probably know you need to slide the feedback coil around the 1B3 to find the sweet spot that gives the best HV.

I tried that, no luck

Low hv, change those domino looking micas and there’s one on the hv coil

Okay

Sad news, the CRT filament went open. I’m pulling all the caps and moving on. Too bad because the cabinet is very good.
