This is the Gold Pin Option Retube Kit for the PRS Archon 100. The preamp section uses six Gold Pin ECC83S's with one balanced for the phase inverter in V5 for a very smooth and rich tone. The default power tubes are the JJ Electronic 6L6GC's. With the customize option you can configure this kit to use the JJ 5881's, JJ 6V6S's, EL34's, EL34 II's, E34L's, KT77's or Big Bottle 6CA7's.
These amps are adjustable bias with test points.
