Tangent’s PPA v.2.0 headphone amp and YJPS power supply.
I have obtained $210+ worth of parts needed for this project however due to life, my priorities have changed and I regretfully need to sell these parts.

I did all the homework for the PPA & YJPS based on the power supply requirements of 32 ohm headphone load however 99% of what is listed here will be applicable for 300 ohm or other load cans.

I have a very detailed excel bill of materials showing all the parts obtained and prices for all materials.

Parts obtained / For Sale

R2 L/R, R3 L/R, R4 L/R, R6 L/R, R8, R9, R10, R11, R12, R13, R21, R22, R31, R32, R23, R33, R24, R34, C2 (3x0.022 & 2x0.22uF), C6G, LED, D1, Q1, Q2, Q3, Q4, Q21, Q22, Q23, Q31, Q32, Q33, Q24, Q34, TLE, OPA627AP L/R/G, Neutrik output jack, power switch, bass boost toggle switch, Silver Hammond enclosure with metal end plates, gold DIP-8 sockets, and Molex male and female connectors and crimp terminals.

Missing for complete build (not included): R1 L/R/G, R4G, R5 L/R, RLED, C1, C4, C5, C7, volume control, volume knob, RCA inputs and circuit board from Tangent.

Missing parts for complete build (not included): R8, R10, R11, R12, U1, U2, C1, C3, C5, D1, D2, D4, L1, 15V transformer, power cord, and the circuit board from Tangent.

I was going for Elna Silmic II’s at C1 on the PPA which you can get from Digikey along with most of the other missing parts, the PCB’s are available from Tangent.

$170 obo. For both kits. I will even include a 3rd hammond enclosure for free.

Serious enquiries only, I can provide the excel BoM if needed. I will consider splitting the PPA & YJPS parts but I wont discount them as much. Please send me a PM if interested.
