The plexi K150 combo – is the amp circuitry like a metal-face K150 or is it more like a modified K100 combo?
Was the plexi K150 combo not available in red or gold (except special order) like the K150/K250?

Hi Les.The plexi 150 is different than the 100.From working on one that I,ve fixed, they have another transformer in the amp. I did not have a schematic for the power supply of the amp, nor the output stage so I do not know if that trans was a choke in the power supply or a step up trans in the driver to output stage. They get the extra 25 watts some how and the amp only had the normal 50 volt filter cans, so the extra watts are not from hotter power supply rails.I will have your 200 ready and the kIII looked at after next week. sorry for the delay.
