Default Quicksilver KT88 mono 60watt amp schematic

Is there anyone out there that also owns Quicksilver amps? If so would you happen to have this model? I would be more than willing to purchase a copy of the schematic. I have contacted Quicksilver and am told that they don't have a copy of this model, how strange.

Default QUICKSILVER.

Hi Joe,

The circuitdiagram for the amp could be drawn in less then ten minutes by a competent technician.

The beauty of that amp is it's sheer simplicity,just a pair of coupling caps and a handful resistors.

None of the customers got the circuitdiagrams with their amps,not even the dealers as I recall it.

Ciao,

Your correct as usual. I could draw it provided I lock the dog in his kennel so he doesn't run off with my tubes. I do however prefer the neatness of a professional job to my hen scratching.

Its nice to see you back!!

I'll draw it out if you will help me hot rod it.

Joe

Default THAT DOG AGAIN.

Hi Joe,

Thanks for the nice words.

There is not much hotrodding involved,just change the couplingcaps and a couple of Rs.

Did you actually listen to it already?

Ciao,

Not knowing much about tube equipment I found the Quicksilvers to be very pleasing to the ear. I was surprised at the amount of bass and the bass wasn't quite as sloppy as the reviews that I had read. The midrange was quite warm and the highs pleasing. Honestly, it put my SAE X25A(class A poweramp) to shame. I'm glad I offered the guy I bought the amps from the little extra it took to get them. The reviews I've read on the amps seem dead on. I believe that you were right also, they are a good sounding amp.

Now, Ive got to finish selecting my parts to assemble my preamp.

Here is a picture of the guts.

Default FROM WHAT WE SEE

Hi Joe,

Your amp has been modified already.
Maybe by Quicksilver themselves,maybe by the previous owner?

At the lefthand side top you see the two coupling caps that are now MIT Multicaps.
The yellow ones are unchanged and bypass the PSU caps.
Most of the resistor look a lot like the Roederstein Resista and these are fine to my ears.
Other than that you see a few Philips metaloxide resitors,a couple of mica caps,all in all nothing really harmful to the sound.

I always found the bass excellent,even exceptionally good on these amps.
The highs should be a bit more open now thanks to the MIT caps.

Do you want the best 6550's for these?
Get a set of matched Tungsols,these are by far the best I ever heard by a long shot.
Magic!

And please don't buy all of what you find...I need about fifty of those a year.

Glad you're happy with your purchase Joe,

Your just downright amazing. When I talked to the gentleman at Quicksilver and gave him my serial numbers he told me the amp had been modified to accept either 12FQ7 or 12BH7 tubes on the front end. From looking at the work/solder joints I knew the amp must be modified. The two caps didn't match the other Quicksilver brand caps. The amp is very good sounding. Is there any other improvements that could be made?

Joe
