Since there were some errors on the schematic, please refer to these values should you need recapping your vintage Ace Tone drum machine:
I have been building Selmer Buzz Tones for a few groupies n fans recently.
Featuring rare 2N2613 transistors on choc brown paxoline board, on eyelets just like the original.
One small mod is the cap tuck away under the board, to give it some juice.
Cheapo build for a friend:
Another build.. featuring the Palenque astronaut..
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.
This must be a very early one, word has it that Jimi Hendrix tried one of these boxes for its big muff-like forced sustain. It is one of the earliest electro harmonix effects.
It is powered by TWO 9v batteries and so much for it “being distortion free”, it is very hissy and noisy, and colours the tone. The compression is VERY apparent and squashed.
Transistors: FS36999, the same as early 70’s Big Muffs.
The tube version Black Finger is a much different, more reliable and usable item.
Was this the very first BBD delay?
Tabletop machine, self oscillating AND from past internet auctions and reviews it is apparent, nobody knows how to determine if theirs is in working order (😂), because it is very temperamental and does a lot of different things.. But when it behaves, it’s magic!
Echo, reverb and has a very weird chorus.
Amazing and beautiful, nothing like a tape echo or a memory man.. Far less predictable!
A delay with character.
