Default FS - DIY spare parts, pcbs and amps (Dynahi, M3, PPAv2)


I'm putting a lot of diy stuff for sale that I don't need anymore.

- Assembled and tested M3 set (150€): these belonged to a project that never found a case . It's a Sigma11 set for +30V output, Amveco 25VA transformer, M3 with dual Alps RK27 for volume control and gain control (gain is variable from 2x to 11x). Opamps are OPA134 on sockets so you can roll them.

- Assembled and tested PPAv2 (50€): perfectly functional and good sounding PPAv2 amp configured for a gain of 8x. I will include a 24V adapter but you can use much better power supplies with this amp. Alps RK27 volume control and rollable OPA134 opamps.

- Balanced Squarewave PCB set (30€): one set includes 4 amp boards and 2 power supplies

- TKD 2CP-2500 50K volume pot (50€): brand new, never used

- 2x Toroidy 50VA transformer (40€ for the set): these were used on other projects but are still in excellent condition. Dual 115V primaries and dual 30V secondaries. Custom made by Toroidy (Poland) with audio grade cores, shielded and encapsulated. Perfect for powering +/-30V power supplies like the Sigma22

I will be adding more stuff soon.
Please feel free to ask any questions.
