OK, I'll bite. Looks like pencil tubes but they seem a little bigger than the ones I have. What are they and what's the amp?

6Ж32Б-В, 6Ж9Г-В. Stereo microphone preamp. SE transformer outputs, 600 Ohm 0 dB. Pentodes with feedback resistor between anodes.

6Н16Б-В in the microphone itself and in a HPF (Sallen Key)

A stereo condenser vacuum tube microphone, with switchable HPF and an optical compressor - limiter.

Going to test tomorrow...

Thank you. The body for the prototype I took from Marshall MXL microphones. :rolleyes:

Octava does not produce stereo vacuum tube condenser microphones with 0 dB output. :p

It's Russia: D: D: D. On request they make any, with any characteristics. Even if you want to cover with gold:п. The factory is 100 meters away from me ...

But your microphone looks super confident that sounds the same. Excellent work

Interesting project. Thx for posting it. Someday I hope to play with pencil tubes for a guitar pre-amp.

Yes, they cover membranes by gold. Mine that were made in USA (or may be in China?) are similar, copied from the same Neumann microphones.

Here is the record that I made when tested mine, it is stereo, and sounds as if you are there:

Top center is the Phono pre? And btw, how do you control tracking force?:D (edit: nice system btw)
yes similar to audio note M10
Mitsubishi LT-5V is designed to work in vertical position :)

Impressive!
Schematics and details of making amplifiers with rs1026, please?

schematics are designed by Noyan Akdulun (he is here on forum too) and he is keeping it in secret,sorry :eek:
details of making? hours and hours and hours working with my hands :cool:
