Reluctantly these will go to make room for all the other projects both kits have been listened to and enjoyed, both work perfectly.
These are excellent sounding amps well built with some nice touches. Please PM any questions. Both are configured for 240V mains but can be easily converted.
Whammy Headphone amplifier kit -
High quality 2mm PCB with 2oz copper and ENIG finish
-Configured for separate front end supply for the op-amp using http://www.ldovr.com/ regulators set for 16V output. Both regs are supplied by the main rails and mounted on a small heatsink braket. None of the holes drilled interfere with any circuit traces so can be reverted without issue.
-Matched 2SK2013 / 2SJ313 Toshiba output transistors from Lubincalvin.
Hexfred Diodes, Elna Cerafine decoupling caps for op-amp and NJR 18V regulators. 25VA Talema transformer with 18V secondaries.
Fitted with OPA1912 dual opamp on BrownDog adapter and Neutrik 1/4" panel socket. Signal wires are Van Damme insulated OCF copper.
Can also provide high quality 100K TKD 2CP-2511 potentiometer ONLY USED FOR THIS PROJECT, STILL PERFECT CONDITION.
Price without TKD pot - £70 plus shipping.
Price with pot - £130
ONE WHAMMY BARE PCB IS STILL AVAILABLE FOR £20 PLEASE ENQUIRE

Richard Marsh Headphone amp kit -
Superb sounding amp built using matched parts from Jackinnj. The amp is offered with the all in one Sulzer dual polarity power supplies from ATLhifi but supplies and ampcan be sold seperately if required. Together they make a fantastic ready to go head amp.
Marsh amp is built onto L bracket and box aluminium heatsink which is adequate when fixed to a metal chassis. Resistors are Dale and Kiwame. Supply decoupling caps are FC's - It is a very simple circuit.
ATL Sulzer supplies - configured for 19V output, very solid supplies with BYW32 rectifiers and OPA37 ultra low noise opamps. 25VA Talema transformers with 18V secondaries.
Looking for £40 for the Marsh amp and £40 for each Sulzer supply
Marsh amp with both Sulzer supplies £120 plus shipping
