Back to the VT-71H

[Chris K]

Hi Tim. The “cherry drops” capacitors in there are pretty cheap, Chinese knockoffs I got in a multi-pack kit off Amazon. I tested them before I soldered them in and they were in spec and not leaky but I’m wondering if changing them out would help. The Wima high voltage caps are the standard replacement caps for that area and should be ok. Then there’s the pesky resonance spring around the HV rectifier Bob messed with a video or two ago. I believe it is in the correct place but I’m suggesting whatever I can to help out!

Hey Chris the hv spring is good because the hv is at 6 kv I also checked the hv caps they look good I’m coming away from thinking they might be a problem. I sent you an email give me a ring when you have time.

The hv I lowered to 5kv max is 6kv and 3kv is recommended so it’s at the happy medium.

Does anyone have an idea if this ts-4h has channel 1 or is it just 3-4

Hey Chris I’m done with this moto I have had it playing for about an hour with no issues and I’m probably going to let it play for another hour. And Chris the nut on top of the hv cage now has a period correct nut, LOL.

Thanks so much Tim! I bet you’re done with it! I can post video of it running once I have it back. Check your PayPal for my thanks and gratitude for your lengthy efforts!

Oh there was lots to be done lots of soldering bad connections I literally went over everything. The final was the vertical size 2 4.7 meg resistors at 6sl7 were new but the actual solder never made a connection it looked ok but it wasn’t and other numerous resistors. L39 was open that’s why there was no video.
