For Sale 6N30P-DR [6H30∏] tube buffer

[noyan]

I built a zero gain tube buffer. Sounding awesome. It works with 6n30p-dr, 6n6p, ecc99, 6n1p types, 6922, 6n23p-ev. Output impedance is 230 Ohms with 6n30p-dr tube.

Could you share a schematic please?

I'm having an EE design for me a Buffer Pre Amp, the following is where it is heading as a Circuit:

" A parallel connected 12BH7 will give a bit more transparency especially in the low frequencies; I can fit two sockets (if you wish) one for the 6SN7 (octal) and one for the 12BH7 so you can try them both."

This is really good work! Congratulations on the construction choices that you made. The power cable from unit to unit is high on my list when I build this sort of project. I am curious about the AC in voltage-- 200 or 120?

Is 6H30 still available as recent production, or is it NOS? Wouldn't want something with a tube that is made out of unobtainium.

I would take the chance since it is compatible with other tubes as well such as the 6922.

I used this schematic.

New production ones are not good. Use NOS, (Before 1990). I have them if you need.

This device accepts between 110-230V.
