For Sale PCBs for a Line Preamplifier based on OPA627

[Vunce]

Vunce, may i ask which power amp have you tested this preamp?
with Alpha Nirvana? with USSA5?

Actually, neither.
I’ve been in a class AB and D mood lately. The amps I’ve used with this pre so far are TPA3255, FH9HVX and Shaan’s V4H.

Sweet! Nice chassis.
Enjoy your build 😉

Did you pick a selector switch?

I used the same type of switch with solder lugs instead of straight pins. 😉
