How about Quasi Complementary Symmetry? All the same topology, N-channel or P-channel.

someone build it and let me know how well it works. . You know you want to build one................... Perhaps nattonrice might fall for it..!!

Fully differential fully complementary symmetry amps are the best. Unfortunately not possible in electrostatic amps unless you want to do serious transistor stacking. . Something for the future....??

Is the BOM for this amp pretty much set in concrete, or are there envisaged changes to parts in the works?

Sacres cows to the golden eared brigade.

I owned a pair of AD2000's They were great for female vocals, but had no top end whatsoever. They ended up as a give-away at a headphone meet.

Yep, that's them - Future Electronics.. IXCP10M90S @ US2.20c each back in June.

There is one problem for those outside tie US with Mouser. They do not supply ixys sand. So, unless a group buy by someone in the US happens, we outsiders will have to source the components from elsewhere.

Oops dunno how I missed that. . Too early in the day here in Aus.

Put me down for 2 sets of boards, and 2 kits of parts.

Seems like supply issue is resolved...

I found that they have problems with not supplying the goods after payment.

High Quality Audio & Industrial Attenuators any comments...?

Everything is "moar bettah" when it's at the expense of quality. That's why we have Bose headphones and cheap opamp amps.

I'm in for 20

I really appreciate all your help, fellas. farnell MCPRW0AWJP184B00 is 10W will it fit in the footprint on the PCB? KOA Speer resistor are 2W rating. Parts Connexion OK.

partsconnexion "kiwame" for the lazy any major parts distributor for less lazy Farnell, RS Components and a few others don't go near the resistance value at 5 watts.

Where's a good source for the 180 kOhm 5 Watt resistor?

I gather that on the amp board that the two circles marked with a + sign next to the 499k resistors are LEDs, and also that the RLED is provision for a ballast resistor for an external LED. Also, where can we get stax sockets worthy of this project?
