Got carried away and have too many amps. I've got a pair of stuffed Symasym boards, ala AAK. Details here: http://www.diyaudio.com/forums/showthread.php?s=&threadid=99739
All the components are on the board except for the output transistors and VAS transistor. I will provide those also. The OPT's are ONSemi MJW0281/0302, Mikes favorites (drivers are MJE 15031/30). VAS is BD 139. The rest of the parts are from AAK's BOM, Vishay resistors, Panasonic and Wima caps, etc.. Only change is the input transistors are Zetex 694b, but I have the 2n5551 available too.
Parts cost was about $175.00, as added up from the BOM. Boards were $25.00 for the pair. How about $185.
Also have two 250VA 35V toroids, which would be perfect for this version. They are new (except trimmed leads on one). They were $54 from PE.
The whole deal for $275.
