  1. Here is a shot of the 400's big brother. Custom chassis, lighting etc.etc etc..... Show's what you can do to your 400 (And dig another 100 wpc out of it). Just finished this one for a gent an hour ago....
  2. Could be the ground going to the meters, or, there are a couple resistors and a couple diodes which are on the light board. These boards are USUALLY in pretty rough shape after 40 years. White Oak Audio Design has all the items to get that amp back into safe operable condition. The rest of the amp is probably in need of some updating ie.... DC Protection circuit, new bulk caps, new back planes, new control board..... They basically are ticking time bombs unless updated. They weren't made to last forever for sure. And when they fail...... Better have some eye protection on. Maybe a cup too
  3. It's probably the light board where the meter inputs run through it. I doubt that both meters went bad. They are pretty reliable. If somebody has been dorking around inside, that's probably it. Look at the schematic, probably an easy fix. Don't disassemble the meters or "Blow" on them or use canned air on them.
  4. I have an extra NEW black 4000t face plate available in case anybody needs one. PM me if interested. Thanks P
  5. Just finished up a system for a friend. Not bad. The new faceplates make many things possible.
  6. If anybody is interested, I just listed 3 4000t original face plates and 1 C-4000 original face plate on the bay. I know there are probably a few units out there that could use a face lift... I also am selling my 2 reproduction, Black with laser etching, 4000t face plates too https://www.ebay.com/itm/392260506340?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649 This is the last of my stash
  7. You should have said something. I could have got them done for you while it was here.... Or did you???? I got CSR (can't remember Shit)...
  8. I hear ya.... As a matter of fact, I have no amp at the moment either. I have 2 more I'm building but I will only say I'm building 1.... The wife went to rock out and couldn't find the On Button... Haaaa, couldn't find the amp either. But it works for the best since I can put a few hours on the amps before I ship them.... GOOD BURN IN.....
  9. I'm glad you use the Easy Gain... The factory made it a sufficient pain in the ass to change the gain and I decided to do something about it. It's the little things. I thought I was the only one who wanted to move their dials into that "Sweet Spot"... Thanks Dick Perry MY issue is that every time I get a preamp set up for my system, somebody up and buys it so it's back to the drawing board... I got a couple in work though so I'll get em set up and TRY to hide one for my home system.
  10. I like to do the 4000t's big time (Minus the remote kits).... did you post a pic in the rack? I powder coated the handles black on this one.
  11. I got em to match pretty close. Anybody need a c-4000??? They most certainly look nice (IMHO)
  12. Yep, I didn't need the help so I declined. I have bought items from him in the past and the quality of the items were excellent.
  13. I guess there is a rumor going around that I worked with Russ K on these faceplates......... that's a big pile of hooey.... He was nowhere in the picture..... he asked, I said no.... end of rumor...
