Jan6418 RIAA Preamp (Turntable)

I designed this about 10 years ago, it sounds amazing. you will need to etch two of these, one for each channel.

I used Russian PETP capacitors, they are a great allround capacitor, good clarity and warmth.

Tubes are the Raytheon Jan 6418 sub miniature pentodes.

I used Russian Teflon capacitors for the filters (0.022uf and 8200pf)
