PLEASE HELP---Sansui 1000A tech question

So, I recently replaced the rectifiers and filter caps in my Sansui 1000A. I think I've got everything hooked up right, but I'm showing negative voltage on the plate...about -520V or so. Grid shows negative voltage.

What's the deal? Obviously I'm getting no sound...doing I have something wired in reverse? Without detailing the setup, I'm pretty sure I just replaced all the previous parts.

Try the classic Sansui forum at Sansui and Beyond. They have fanatics extremely knowledgable about anything and everything to do with Sansui's.

I recommend to bring it to a reliable Tech before the problem is amplified to a real one. I am a Tech myself but I live in Vancouver, Canada.

You have replaced the parts reversed, not good, 1000A power supply usually holds up well as original, oil filled caps are ALL bad, have restored least 6 of 1000A and a 1000 in the past year, they all sounded very good when done right.
