I am looking for replacement transistors for the ps/protection board.(F-2663) TR01,02 are 2SD356, and Woodang shows a replacement avail...2SC2168. however;

TR03,04 are 2SB526 and Woodang shows no replacements. Can anybody recommend a high quality source or equivalent part # for these parts? Any help appreciated.

That's a TO-220. Use a MJE15032 (NPN) and MJE15033 (PNP).

Perfect..Thanks..
Who do you recommend as a supplier? Also, I found this little reference chart on the web. It might be helpful for specs and cross-referencing. I really appreciate YOUR input EW, because I can trust that your recommendations are based on experience and positive results.

Digikey may be out of them, but they are worth waiting for.

A cross-reference is fine, but the parts I recommended are much much tougher than the originals, the point being that you use them and never have them fail (which is always the goal).
