  1. So Bob spelled backwards is John? Sh!t my name is John!!! I suck at all this eschatological stuffs.
  2. Welcome aboard the OCCD train! lol Plenty of good folks here with a wealth of knowledge. You'll have no problem finding what you need to bring your Carver up to snuff in no time.
  3. Welcome!!! I've done this all of 2 times on old guitar amps in my 5 decades on this planet. This is how I did it (more than one way to do it). (I found a version of the same technique online- but there are other techniques) I made sure that the correct fuse was installed in the amp(s). Cleaned them up on the inside a bit to look for any obvious signs of abuse or failures (burn marks, already blown caps, missing bits, etc) Then I took a volt meter and measured the wall outlet voltage when it would be most stable (usually late evening/night). Then using the volt meter, measured the output voltage of the variac at unity. (or noted where unity was on the variac's meter--not always correct). I didn't want to over power the amp. Made sure that the correct ohm load was connected. (cheap speakers or dummy load). No signal! Volume down as my guitar amps obviously had preamps. You're amps don't need a signal. Now the key is to give the caps some time to form at low voltage say 40% or so at first. Just slowly turn up the voltage on the variac in 5-10v increments...waiting for a few minutes at each point until you reach 40%. Hold there for an hour. Turn up the voltage at 5-10v and hold for 30mins. Keep doing that until you get to full voltage. Hold there overnight. The next day I carefully turned down the voltage on the variac and turned off the amp- unplugged it from the variac. Then I ran them for a few days at low volume with a signal going into it. I noticed that the sound changed over that time. Maybe your mileage will vary...but it seemed that the amps needed some time to 'recalibrate'. ?? Then I jammed away! No issues. I did take them into my local tech to have them 'gone thru' before I gigged with them. I'd do the same thing with home stereos that have been sitting for a while too. Just to feed my OCD.
