SV: TB-303 original power supply - Answerfrom author

[*Star Project]

RE: TB-303 original power supplyThe thing is that i am building a exact copy
except from
hopefully the powersupply. Synth part and sequencer.
The thing with the Oakley sound system TB-3030
that you suggested is that it uses substitute parts
and has all that extra that i dont want.

I would really appriciate a schematic for that reply
with a suggested IC and the lithium battery to back
up the memory with.

  Are you going to clone the sequencer part too?
  Why don't you take a look at http://www.techrepairs.freeserve.co.uk
  There's a TB303 clone (only the synth part) complete with PCB and (good)
documentation. It's more than just a clone, it also features a suboctave
generator, HF modulation of the filter, adjustable slide time, a distortion
unit etc. Check it out.
