Hot Rod Deluxe no More Drive

And what are the TP35 voltages?

TP35 was low, around -8v I don't know why, I replaced cr24, 26, c47 and r96 measures correct.
After a couple hours warm up, K1A wouldn't fire with R84 at 1k, unless switching between red and yellow channels.

I restored it to130 ohms and lowered the voltage at TP34 and it's been working.

Well, if nothing else, there's now this event within the history of how the circuit works, and up to someone else who has to time to ponder why. Thankful to see it back and working as it should!
