KD 503 comes up as a 2N3055 type clone by Tesla, with 20A Ic max.

The information obviously comes from hifi-forum.De. You would have to join that forum to request more details about their projects, though I doubt they actually have more than you can see in the thread shown here:

You can try this one - my version of Hungarian B5 power amplifier.
Easy to build, good sound quality.
