Hello all!
Abacus Audio Aikido Tube Preamp. This is the 6GM8 version, not the 12AU7 version. The preamp has the John Broskie Aikido tube preamp PCB - the LV Aikido circuit (low voltage). The 6GM8 (6N27 / ECC86) tube is perfect for this low voltage application - 24 volts B+.
You could drop in another tube like the 6922 or 6DJ8 (do not put in a 12AU7, you will destroy one of the two triodes), but those tubes are best run with higher B+ Voltages...the best tube is the 6GM8 (per Broskie)....and unfortunately they are not cheap.
Comes with extra 6GM8, and programmed remote that does volume, input, power, standby and mute.
Audition possible for those in Chicago area. How's $525 for a ready to go Aikido?

Not that I know - I kinda think he was a DIYAudio guy selling off some nice preamps...The one I got was pooged by the previous owner and I had to rebuild the whole unit from pics of the PCB on the internet.
New owner really likes the preamp.
