My TO3 version of AX11 for more power.
Used BD679A instead of MPSA13
MJE15030/15031 instead of BD139/140
MJE340/350 instead of BC639/640
MJ15003/15004 instead of BD249/250
Also you need 2N5551 or 2sc2240 instead of BC546, if you use higher voltage.

Just another version...
with common heatsink for the driver (not tested).
regards Olaf
Nice work,
Regards
Cant wait for it to be released,i will build this as soo ans the common heatsink one gets released
Hi, the module is tested and works well. The sound is warm and clear and crisp and powerfull in the bass. I like it.
Heatsink comes from a old PC-grafics-card. All transistors stay cool.

No, there is only a far, distant noise on open input, should be normal because the circuit was completely open and not shielded.

Hi Shravant,
See attached maybe this a bit better than the previous file.
