I have the K100-5B on the bench. My experience has been primarily tube amps.
This amp powers up. It produces a loud swoosh sound. Not a hum as much as a dull roar. It is consistant and not effected by rotating any controls of the four channels.
I get output from all channels although channels 2 and 3 have a little less gain.
Reverb works.I have installed a grounded power cord. Measured +-38
vdc off the large caps and +-8vdc on the four preamp pcb wires. It appears to have original RCA transistors.
The sound is less like a hum than a rushing swoosh noise. My hopes are that one of you more experienced Kustom gurus can steer me to a logical area to test.
