At a hamfest last year, I found a bargain power supply which needed just a little repair work. Now I know why it was so cheap! I need to replace some 2SD845 power transistors in it. Unfortunately this device and its replacements are no longer manufactured and I can't find anything to substitute which will fit the heat sink and circuit board (without major surgery). Here is my list of possible substitutions: Number Pd(W) Ic(A) Manuf 2SD845 120 12 Toshiba (original part) 2SC2562 150 15 Toshiba 2SC2921 150 15 Sanken 2SD745 120 10 Nippon 2SD852 100 15 Nippon 2SC2650 100 10 Toshiba 2SD851 80 10 Nippon If anyone knows where I can find about 4 of one of these, please let me know.

Unfortunately this device and its >replacements are no longer manufactured and I can't find anything to Call MCM Electronics at 1-800-543-4330 and tell 'em you want a 2SD845; they have 'em. You might have to buy more than one to jump over a minimum order. --------------------------\ /----------------------------------------------- INTERNET:tindle@ms.uky.edu | "Could you please continue the petty bickering?
