Hi all, in desperate need of some info or possibly a source for some replacement Schottky diodes used by SAE in their "X" series amps, in my case, an X-25A, it has two diodes in each channel, between the commons of the emitters and the opposite polarity's output banks Vcc. Here is a link to the print of the output section of amp: http://www.wardsweb.org/audio/docs/X25_schematic2.tif
The parts I need or need information about in order to replace them are CR-14 and CR-15. They are both high current Schottky diodes, stud mount types. Both are at least 40 to as much as 80 amp devices, this much is obvious, the other specs about the diodes are a mystery to me. SAE had them made for their amps by TRW at the time of manufacture, some where around 1980ish. SAE's part number for them is 11-0202. I've been repairing and re engineering this sort of gear since about the time this amp was made, and I've never run into a part so shrouded in such mystery. There justs seems to be one dead end after another researching these diodes. As I really am not an engineer, just a humble tech with some knowledge, just enough to be very dangerous, I'd really appreciate any help in this matter I can get. I'm "chompin at the bit" to hear this amp running but until I can sub for these diodes I'm too chicken to just start guessing at the specs to put new ones in to try 'em at random. Please I'll gladly take any help you all can come up with. Thanks in advance, Steve
