View Full Version : Detailed PRS Amp specs?

12-25-2012, 09:20 PM
Are there detailed resources for PRS amps, like schematics or just tubes used? From personal account, tube use seems to vary from amp model, widely.

Taking my personal needs as an example, the Super Dallas that I have is loaded with the following:

V1: JAN Phillips USA 12AT7
V2: Tung Sol Russian 12AX7
V3: JAN Phillips USA 12AT7
V4: Tube Amp Doctor 7025WA 12AX7

The power tubes are Winged 'C' SED EL-34s.

Is this typical? Or did the previous owner go on a preamp cocktail binge? I'm not even sure that V1 is actually V1 (listed left to right from back of amp). It would make more sense to me that V4 is actually V1 since a the TAD makes a nice primary influence and a 12AT7 as a phase inverter would be an interesting change to what I'm used to. Any documentation known? It would be nice to be more technically fluent in the amp I'm about to devote so much energy to. ;)

I don't know what's in a Super Dallas that's stock, as the tubes aren't listed. But the tubes that came in my HX/DA are listed on the website:


Mine came with JJs in the preamp section. If I had to guess, I'd say that your predecessor may have done a few preamp tube experiments.
