BOARDS ARE SOLD! thank you
Hi,
have 2 boards of this headphone amp to sell. Pretty recently assembled.
Matched transistors and working & sounding very well.
(tested with Sennheiser HD598, 50Ohm)
This one makes a lovely preamplifier as well.
Gain & bias currents can be set-up for whatever you like.
[The zener regulators are currently not populated as Ised an external regulated power supply.
The transistors from the regulators are bridget using a resistors, forming an additional RC-filter.
I could easily populate according to the original BOM if one wishes.]
Simply have to declutter and get rid of a couple of things that don´t get any use.
2 populated boards for 30€ + shipping.
Despite the declutter, one thing I´d be willing to trade with is a 2x24VAC-transformer (or 2x26VAC max.)200-300VA.
Best regards
Jens
