Esteemed Electronics Experts: This may be on topic - it's for an old piece of test equipment with an NEC V40, an Analogic 2030 function generator. Anyway it's blowing fuses - traced it to a shorted diode in a power supply, marked (Motorola Symbol) ZP 1N 540 905 Don't think it's a 1N540 - top hat silicon - this one just looks like a fat 1N4007 cylinder. Not a 1N5409. 1N540905 doesn't exist in google-world. ---(==(--- Any tips, actually just want ratings for replacement TIA --Chuck
