Specs from the Auction:
- The TM3030 is a midi controlled bassline clone that is designed to sound good.
- The design features the same controls as the little sliver box we have all come
to love: tune, waveshape, cut-off, resonance, envelope sweep, decay time, accent and volume.
- Slides and accents are faithfully reproduced.
- This unit contains no internal sequencer. The midi interface is controlled by a pre-programmed microcontroller chip.
- The rear panel houses the audio output, DC input, power switch, midi through and midi input sockets.
- The front panel pots are Alpha 16mm aluminum devices. These offer solidity, long life and feel good.
- The front panel LEDs show slide, gate, accent and power on conditions.
- The power requirements is 24V DC. The unit comes with us power supply.
- For the FET buffer of the VCO I used the 2SK30A-O and for the differential amplifier I put a 2SC1583
like the original design of the Roland TB-303. For the VCA, I used the CA3080 OTA.
- To achieve the best resonance, I replaced R62 with a 6k2 resistor
and 10k trimmer in series, and adjusted the maximum resonance to match my real TB-303.
