This followed me home yesterday! Pretty interesting relic of (best guess) the late 60’s. 6CA4 rectifier, two 6BQ5 power tubes, and a pair of 12AX7’s. I stood on a rubber mat and played bass through it for a bit. Not horribly noisy, neither buzz or amplified bass volume but it would probably work with a light handed drummer. The last bit of the volume knob will bring about some distortion but it will hang on to the bitter end. Going to put in a grounded power cord and remove the death cap before plugging into it again. I’ve been wanting to build a tube bass amp for some time. Going to spend some time with this and get to know it for awhile. Based on the size of the iron, I’m guessing there’s some room for improvement here.
