Yeah, I may regret this one....I built this many years ago and has been my "Standard" preamp for years. The preamp is an Aikido All In One Noval Broskie circuit board with 6N11 (6922) in front and 6N1P in back. Nice caps too...
The Phono Stage (on AUX) is a Hagerman Bugle (first gen?) and works perfectly and has the LM4562 op amps.
All in a very nice and clean (and heavy as heck) ARC style chassis that was quite expensive when purchase over 8 years ago.
Like all Aikido preamps, and many DIY Tube Preamps that do not have muting circuit, it makes a few noises on startup before completely powering up... I always started it , waited 30 seconds and then powered up amp - and reverse order for shutdown.
A tube roller - circuit tweakers dream preamp!
How's $650 + ship?

Very nice build 🙂
Just to correct you..... 6N11 is NOT the replacement for 6922/ECC88/6DJ8. The correct russian tube is 6N23P.

Thanks - I think it originally came with 6922 in front and 6NP1 in the back. Sounds quite nice with 6N11 in drivers seat so thats how I had it for years...
The four cathode resistor are 300 ohm each channel...so set for for the 6922 family...

According to this chart, 6N11 is the Chinese version of the 6922...

Edit - Front 6P11 tubes replaced with pair of 6922 EH...
6p11 tubes went to another member who needed them....

Yes, agree! If I didn't love my Music Reference RM5 and Melos SHA GOLD so much I would keep it!
Thanks!
Thanks!
Hi John,
I just want to tell you that you have done a beautiful job on it. You should know that. Too bad it doesn't have a phono stage and a muting circuit.
