Hohner Basset

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..


Keyboard:

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.

Video below..

Pcb: 3.1967!!

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

Hohner Cembalet repair

My beloved Hohner Cembalet I has gone silent, all of a sudden.

Here we go with a few pics i took for reference of the main board.

They may help someone else whos trying to fix his Cembalet.. I hope.

Schem and user manual (in kraut):

Update: the Cembalet healed itself and now it works great. I did not have to do anything to it, it just works again, magic, bang.

A friend who’s an electronic repairer said that the most important part to watch out for is the inductor (Spule in german), as it’s custom wound to specs for this instrument.
