Hi Tube Nuts,I may be insane,but want to try and get a couple of Dyna PAM-1's souped up and running.I have the Dyna Mark3's needed with the octal tube socket that provides the PAM's,mono preamps with the heater voltage.What I want to know is it possible to take the tone controls and the loudness switch out of the circuit?I found a copy of the manual on line and am going to try to post it with this question.It has a real big picture of the lay out plus the schematics and all the other info.If any one has an idea,I would love to hear it....thanks....Mark Kordahttp://www.the-planet.org/dynaco/Preamplifier/PAM.pdf
