No wonder I got the last 6 they had in stock, you had most of them! Profusion only had a1295-O & c3264-O. I believe these are selected as lower gain version than the 1295-Y & 3264-Y (according to Sanken data hFE Rank O(50to100), Y(70to140)). I am in the process of fixing a Malcolm Hill designed Chameleon power amp which has 1 pair blown of the Y variety (higher gain. I don't think -O variant is OK to parallel with -Y type. My existing good transistors have hFE of approx 140, high up in the Y gain spec.) it has 5 NPN and 5 PNP per channel in parallel for a rated 700W per channel into 4ohm.

I ordered 50 each A1295 and C3264 from Newark in February but didn't receive all the C3264's. I just got a notice that the rest of my order shipped - I had completely forgotten about it. Both types are in stock at Newark/element14 now. Their description gave hFE as 50 but I received all Y-grade. Looks like there are 438 C3264's in stock and 266 of A1295.

I may be wrong but it seems to me that Sanken's mt200 transistors might be the 15A ones attached to a MT200 bigger plate. That's how it looks when you open mt200 transistor.

cheers,
