When i bought it it looked like this
I opened it up to clean it and realised this wasnt its original colour.
It really was taupe gray before, but the years had the plastic chassis yellowing
I decided to restore it to its original colour (or as close as i could…)
After 5 months of great fun, I had to open it up because the output went silent.
Gutshots of the Hohner Basset!
Lets start with the DIN jack that connects it to the bass amp..
Circuit board and caps jungle:
Inside the white enclosure there’s a lamp and a ldr.. this assembly is the actual “percussion” section.
You press a note on the keyboard, the light goes off slowly (sustain) according to the knob position, when not in auto mode.
Ahem this means the caps have been doing their job for 50 long years! Only one of the capacitors has failed, please note- the blue valvo 100uF cap now measures 1uF!
Output DIN and 3 pronged jack, fuse
