Nothing wrong, simply the 2N5401 is more easy to find.
Those MJE15030/31 are eletricaly ok but TO220 case.The originals are TO3 no ?
Replacements, also TO3, can be MJ21193/94;

I have quite a big amount of ksa992's so that's not a problem.
Nope the drivers are TO220 cases mounted to individual heat sinks. only the outputs are TO3.
Ah yes, the drivers.The MJE15030/31 are rather for the finals.
You can replace the 2SC1624 with TIP47...50 and 2SA814 with MJE5730.
Or the MJE340(npn) MJE350(pnp) They are in a TO126 with the connections inverted (to mount 180° turned)
