    Re: Should I power this thing up?(I HAVE NO VARIAC)

    My Sansui power amp uses two 80v 22,000uF mounted in a metal ring. To keep the same diameter 77mm and close to the same height 100mm, I had to go up to 100v. Only two companies made them and nobody had the Panasonic. I bought Epcos from Farnell in London for $100 each. Mouser wanted $200 each for them. The new were 105mm tall and just cleared the top by a mm or two. Main thing is they work, not bad for forty year old technology.

      so super high value caps are becoming a rarity? or no?
      Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

        no, but they are getting smaller.

        personally i just drill the chassis to hold a smaller mounting clamp or put a colar around the cap to bump up the diameter.

            is it bad when I can drive intercom speakers that use a transformer and not have a problem?
            Also, how can I remove the non-soldered wires from the boards w/o cutting them?

                Don't remove those wires at all. Just move the board as easy as you can. Look up wire wrap. You can unsolder the pin if you have too.

                      That's what most people do. I try to keep them looking the same as new for the most part. I've rebuilt five examples of one amplifier already and have three more to do. Panasonic announced they were going to discontinue the cap I use. Since it has two caps for each channel, I ordered up about $300 worth of them caps while I could. Going up to 80v from 63v kept the diameter the same but the new were still about 10mm shorter than the original. It works though and they are solid black like the original elna.

                        why not remove the wires from the pins? too much risk?

                          Temper temper young man. I thought I did answer. Look up wire wrap. Don't cut those wires at all. Just move the board around as easy as you can because they are solid core and will break. If you absolutely have to remove one, unsolder the pin it's attached to from the board.

                            First problem is originality, it's hard to wire wrap if you don't know how. Takes practice just like soldering. Second is keeping track of where each wire goes. One miswire can cost you the whole project or at least a lot of trouble.

                              Unsolder every last pin?

                                  It can't be that hard. Pioneer is bad with that wire wrap and I managed to get the boards lifted an inch so I could get to the bottom of the boards. It takes skill and patience but you knew that. Not everything in life is easy. Work on cars or airplanes enough and you learn that. Sometimes where you need to go is just barely big enough to get a hand into but not big enough to see in it and it's full of sharp edges so you pretty much pull out a bloody stump when your done.
