Peach/pCATS with Telefunkens

Recommended Posts

Rockhound sold me another Peach, and I replaced the 12AX7 tubes with Telefunkens. My Khorns and I love the change! Thanks to davis419b sending me an email from Mark Deneen,  I just ordered a quad of them for the pCATS. I was going to replace the KT88s, but Mark wrote that the improvement was to be had in the drivers, so I'm looking forward to getting a quad of Telefunken smooth plate 12AX7s from Brent Jesse to go in the pCATS. Don is also sending me a copy of the pCAT manual. Thanks, Don; mine is buried in a pile somewhere.

So, I ordered a matched quad of JJ Blue Glass KT88s to try in the pCATS after I listen for awhile with just the Telefunkens added.

You'll love the Mullards! No remorse here, lol. The Telefunkens really make it shine.

i really enjoy the Old World tubes as well. Mullards, Teles', Amperex, etc. Prices are really going up, so get a stash while you can!

Its been a while since I had a set of PCats here but I do not recall them using a quad of 12AX7's....maybe just brain fog on my part.

Must of had to build up a boat load of gain to drive the phase inverter transformer. If that is the case they probably do make a pretty large sonic change brand to brand.

that is probably the overall gain of the amp..

Yes, but actually 29; my fingers are old. The Telefunkens are far superior to the EHs. I had to listen after 48 hrs of burn-in: Detail, tembre and separation of voice and instruments is delicious.

I didn't expect the JJ Tesla KT88s to make much difference. I was wrong. I like them much better than the EHs.

The russian made kt88 tubes seem pretty high in quality.

Does anybody have Mark Deneen's email? I want to see if he can do a repair to my Blueberry. Thanks.

I don't believe he is in the audio game.  He has not responded to my email from more than a year.  Craig at NOS Valves is familiar with the Blueberry.  What is wrong with yours?  I believe there is a known issue about the heat sink loosening on the rectifier IIRC.  It led to a failure in my buddy's.  It was a cheap/easy repair.

The fix for mine was when Craig went through and started reheating every solder joint.  One was probably broken or had a bad connection due to being slammed around in shipping.

I had a rca jack break off.  I can get someone else to repair it, but I wanted him to. Thanks.

That's pretty common. I broke one when I disconnected my original Peach in order to hook up another one that I bought. That whole array of jacks is flimsy.
