As for Q1 and Q3: replaced with +100 4a 30w 863-MJE15032G npn to-220
-100 4a 30w 863-MJE15033G pnp to-220
I was speaking of q1 and q3 power pass elements, there are the sziklai pair's opposite polarity drivers of q3 (2sa733 > ), q4(2sa904 > ) to consider.
If you really used a 863-MJE15033G pnp to-220 in place of a low power high gain 2sa733 pnp in Q3, I'd like to know WHO recommended that. :nono:
edit - the pictures don't agree... they seem closer to my parts list below.
Q11 and Q12 are the only TO-220 transistors provided for on that board.

But it looks like you need some 2sk34's which are getting rare, because they are 50v parts
You can TRY a general jfet (maybe a j113 or similar) and see if that works in the supply. It is a 35v part and still is common.
I understand that being in Taiwan makes parts procurement a bit more difficult.
