For Sale:
M^3 Amplifier & Sigma 11 Power Supply (Amp & PS)

Will Ship To: Anywhere

A wonderful amplifier. I've used them with tremendous pleasure for about 7 years. I cannot find the original listing for the M3 amp in the archives any longer, but it was constructed by Vaughn. More to the point, when there were some heating issues, the illustrious FallenAngel (Pavel Boiko) rechecked all the solder-points and hand-constructed the Sigma 11 power supply. People who remember FallenAngel will recall the exceptionally high quality of his work.

 

Answers to questions about component parts:

 

The op amps are 8610As

 

The transformer is a Lundberg - Y236053

 

The pots are genuine Alps - 829G 50KAX2

LAST CALL

 

International Bidders: I will sell to headfiers with more than 20 posts outside the US, but you must contact me for detailed information about shipping costs and times.

The asking price for the M^3 Amplifier & Sigma 11 Power Supply has been reduced.

Spring Break (mine) price reduction. I've got a week to get outstanding projects done. The timing would be good for sending this superb amp to someone.

Last call folks! I'm not sure why the M^3 has fallen out of favor, but I'm surprised that nobody has approached me about details.

Does this have the bass boost, and do you know many amps the psu outputs, and any other info that might be good to now.

From what I saw on the net these were things that could among others be changed.

Yes, the bass boost is fully functional. As they say, it's a subtle difference, but it works well as a 'tone control'.

I've put up additional, slightly better pictures of the M^3 Internals as well as a picture of the Sigma 11's wiring and toroid.
