for sale:
SFR 40.- (used to be $40) plus shipping. (approx 5.-)
sorry i can not give prices in $ anymore. free falling.
this board contains:
-riaa encoding (switchable 75us time constant)
-feedback preamp mixer, and
-feedback monitoring section.
all parts can be bought at mouser or any electronic shop. i used through hole parts only.
the preamp works for caruso preamp, sc99. neumann es59,sx68,sx74, ortofon heads. for stereo you need 2 boards.
there a few parts which are specific to adapt to the head and prefered cutting premp for best performance. but in general it works for any cutterhead. you can also use for non feedback type heads. just dont use the feedback.
additionally you need a good and nice +/- 15V powersupply. (transformer, rectifier a few caps and 7815,7915) and a case.
depending on quality and parts the whole project for a stereo version
will cost you $200-400 in total for all puls 1-2 days of time.
schematics, parts list will come with the board. i will also post the schematics. as soon as i built it up myself. including pictures and infos...
and if you ever buy (yes its still my fault...) i deduct the sfr 40.- on your caruso buy.
