These amps had very tight operating tolerances and generally require servicing from a knowledgeable tech on a somewhat regular basis. They are excellent amps and are very dynamic. If you do buy the 433 and run into an issue I have the HPA schematics that I could send to you. From my experience this series of amps has no cap problems.
Many years have passed ... you would have the schematics of the Proceed HPA. I have a 3 channel problem and I can't get this schematic anywhere ...... Thank you very much!
