Audionote M3 preamp circuit.
Hi-whilst idly searching the net looking to see if i could find a preamp design which used an ECL82 (cos i have a couple spare) i came across some "rave" reviews of a new version of the Audionote M3 which uses one in the power supply.
I would like to see the circuit diagram for this,has anyone got a copy ? Philip

Re: Audionote M3 preamp circuit.
That would be interesting, as I am just sketching out a 300b supply that uses one as the control tube (as mr Bench, with a twist)

I thought a preamp would be nice,the EAR still has a good secondhand value and would finance a high spec build,or perhaps a series 3 WD Pre + phono,its tempting ! Philip

Re: Audionote M3 preamp circuit.
Phillip, I have an M8 and can tell you that the power supply also contains a
6X5 rectifier and an OB2 voltage regulator. I beleive it is one of Andy Groves more 'wacky' power supplies. I do not have a cct diagram but I could take a picture of it if you like. Alternatively if you look at the Audionote website you can see the board on the pre-amp and DAC section where it is also used.
