I was playing with the TS-18 last night and I remembered something. I never replaced the selenium rectifiers. I checked the B++ and at 120 volts it has 247 volts. It stabilizes in about one minute. I checked my TS-4J at work today. I jumped the seleniums decades ago with silicons and it has been very unstable. I removed the silicons and just turned it on. It came on in sync and B++ is a bit low at 230 volts. No problems anywhere right now. Good width, good vertical size and the slow contrast warmup is gone. I'm going to let it play and watch the B++. I'll also hope that the "pop, pop and a disagreeable odor" as described in the service manual doesn't happen.
One other thing, the amperite does not light up as bright on turn on. I can't see the inside of the metal ballast on the TS-18 that good on turn-on but I use a variac on that set to protect the ballast.
