For my first post, I looked for an Introductions or New Memeber topic, however I did not find one. I will leave some info here, but if there is such a topic please direct me to it.
I am a 40 year Peavey amplifier user. I have an A.A.A. in Electronics Engingeering, a B.S. in Electrical Engineering, and I maintain and repair my own amps. I am not an amp technician, so there are times it will be me, a schematic, a DMM, a signal generator, and an oscilloscope sorting things out. But so far I have been successful in my endeavors. My formal education included no tube theory or applications, only solid state devices, passive components, and a lot of digital devices and systems. My tube and related knowledge is from books I have read, my experiences, and info gleaned from helpful people on the Internet. It is weird but I am quicker resolving my tube amp issues than my solid state amp issues. Probably because my solid state amps never seem to have issues to begin with. In the past 30+ years I can recall replacing a rectifier diode in a solid state amplifier. I like to say, owning a solid state amp is like owning a clock radio, and owning a tube amp is like owning an automobile.
I have also worked on friends' amplifiers, which brings me to this post. I am helping a friend who has a Peavey Studio Pro 50 with a Saturation issue. As you increase the Saturation, the distortion becomes fizzy/muddy, not the usual Saturation distortion. He has the schematic, but no board/component layout. We could trace the components out on the board, but that is going to be inefficient.
I contacted Peavey a week ago, but they are still on limited staffing due the pandemic, and I am confident priorities are different until they get back to normal levels.
I have searched here, but could not find one or did not have to necessary search terms. Does anyone have a Studio Pro 50 Board/Component Layout you can share? You can email it to me, if you do not want to post it here.
I truly appreciate any assistance.
