Hi everybody.
I built the Borbely low-voltage hybrid Tube-MOSFET opamp. My problem is to find the MOSFET 2SK216 & 2SJ79. I find the 2SK216 at Farnell, but the P-Channel 2SJ79 is out opf stock. Does somebody knows a replacement?
I built allready a preamp with this very good sounding circuit and I would be very pleased to rebulid the same circuit to use it as a filter to improve the sound coming from the soundcard.
Hopefully somebody knows a replacemet.
Thks Martin
