I don't really care if it changes the sound, as long as it's making the
amp sound the way the designer wanted it to. Though seriously, most non 'hi fi' jukes, this really isn't very critical, since the amp designs were pot shots anyway (true of any amps until the 50's or so). |

"Mike Purcell" wrote in message ... I have had a few people tell me to recap my 52 AMI "D" and I have a cap kit on the way. But so far no one has told me what effects this will have on the sound?!?! In fcat I have had at least a few guys tell me not to recap as the amp then looses its "warm" feeling? So they seem to think recapping is abd thing not a good thing. I know its good to help preserve the output xfmr but am I gonna hat ethe sound afterwards? Thanks Mike Purcell Full Tilit Amusements I do tube amplifier repair and rebuilding for a living. The number one thing that happens in here is replacing dried out and or/leaking capacitors and out-of-spec resistors. In my own amps that I am building, I have tried using carbon composition resistors and Sprague capacitors, as these are supposed to be the Holy Grail. One prototype I built using Illinois caps and carbon film resistors is one of the most popular I have, so there you have it. That being said, recapping your amplifier and changing out of spec resistors will help preserve your other components as well as bring your amp back to proper function. Though I once was a hifi junkie, I now regard preservation of old capacitors and components as voodoo and compromising to the amp's existence. I have yet to have ANY customers tell me they liked their amp better when it had leaky capacitors. I think a lot of people think their amps sound great because of the old components, yet they REALLY love their amps when they have been given "the massage". A lot of guitar amps of yesteryear have been "re-issued", and the new amps are not what the old amps were. A lot of people attribute this to new components, but in my opinion, it has more to do with the transformers and original amps being equipped with superior tubes, as in Mullards and black-plate RCA's. Another factor has to do with the new amps being built with cheap circuit boards with thin traces, and traces too close together. There ARE amps with GOOD circuit boards being made, like VHT and Bogner, but this is not the case in the mainstream. Roy |

Roy, I agree with you on everything you said but for me, they simply sound
better. Jim "Roy Blankenship" wrote in message .net... "Mike Purcell" wrote in message ... I have had a few people tell me to recap my 52 AMI "D" and I have a cap kit on the way.

Sir, I don't understand your comment. The question originally asked was why
would one want to re-cap an old working amplifier? I answered "They simply sound better", leaving out all of Roy's comments of course. It sounds, from your comment here that you thought I said they sound better un-recapped. Jim "Sir Cumference" wrote in message ...

I'd recap the amp because it'll save your transformers from smoking, and
make the thing quite reliable. Sound 'better'? It'll sound the way the designer intended it to, since all the voltages will be right and today's caps are actually a bit closer to the textbook ideal capacitor, as opposed to those old paper wax jobs which stunk when they were brand new. |
