PCB Kits for the Richard Marsh Headphone amplifier, these are the improved boards of RM Marsh original schematic, designed by Prasi.
They can use multiple types of output transistors. Kits have matched Toshiba 2SA1930 & 2SC5171 and sound superb.
Kits include two Marsh HPA boards, one Golden Reference PSU and matched set of Toshiba BJTs. - £20 plus shipping

Also selling HiFiSonix (Bonsai) SMD HPA with golden reference PCB plus two Extruded heatsinks, I will include a set of matched Toshiba transistors. - £15

@passive420 I sent you money some time ago for boards and I never received them. You also stopped replying to my DM's asking about them some weeks ago. What is going on? I'd like the boards or a refund please.
If this is of any help I have bought parts and pcbs from passive on 3 or 4 occasions and it was all fine.

All good now folks, many thanks for the support here, Greg, Roar and Steven, diamonds all of you.
Had an infection from operation, got very poorly and it knocked me sideways for a bit. Kind of a depression, couldn't look at the computer, just read books.
Chris has been made good, we are friends. My shameful lack of response is not my way. Apologies Chis, second package on it's way.

Glad you're back in business. Post-op infections can be nasty and particularly draining. Onwards. Upwards
