ok got it! thanks for the advice..
I didn't know how to compare before but based on your advice and spec requirements, the 2SC5198 is an OK replacement. These are some old transistors I found somewhere.. :D
Hello audioguru,
can I ask which of these transistors I can replace for 2N3055
2SC5198

2SC5198...
I was gonna ask if you've revised your schematics.
Found it though! :D
I've been creating different power supply from different sites with different designs and it seems I'm not satisfied with the results.
Anyways, can I replace 2N3055 with Toshiba's 2SC5200 or 2SC5198? This is what I have...
