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.

The pads around some holes look very small.
Is this a pic scaling problem, or is it a true reflection of the copper area available for soldering.

In my view these very small pads are far too small.
