HI first of all sorry if I have not been here for such a long time
Hint of snow this morning so I am not going to do much in the freezing cold loft
I got batch of Diotec measured up PNP mean 380 NPN mean 440
so still no dice
I ordered same more Diotecs from Conrad's and I may get Lucky

One thing standout about the DIOTEC the HFE match on the batches is really good
is just bit of pot luck to get 2 batches that match

time to resurrect this.

I need some 327 in the 430-450 range and some 337 in the 410-430 range.

Please let me know what you have and need i have 500 transistors all grouped to the nearest 5, so 400, 405, 410 etc etc.

Don't give up. I'm still waiting for the pre-regs to finish my paradise. When it is up and running, I will know for sure which transistors I don't need anymore, and will make them available. Others may be in the same situation as me.
