maybe not 😛
my two trafos weighs in at about 10kilo, each
and they are only 2x38V (2KVA)
so if you want twice that voltage...
my usual layout preparation exercise 
anyway...if I really is going to do this, I have decided for a pro style 19" rack box, with heatsink both sides (300 x 165mm)
to get enough heatsink surface I will use one side for NPN output, and other side for PNP
input/VAS will be placed on a long board connecting the two sides
input in the middle, and VAS closer to driver/output

That's much better. Those thin copper tracks wouldn't withstand high current flow. At least 400mil wide track or polygon should be placed, like Apex showed. 😉
