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 http://www.toshiba.com/taec/components2/Datasheet_Sync/66/7886.pdf 2SC2922 http://www.sanken-ele.co.jp/en/prod/semicon/pdf/2sc2922e.pdf 2SC5198 http://www.toshiba.com/taec/components2/Datasheet_Sync/66/7890.pdf I have these transistors in my work bench and if possible, I could use them in this project. ;) But I don't know if it can replace 2N3055. Thanks in advance!

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 for now.
