I seem to remember that someone on this list mentioned a Mouser part number for a suitable Vishay Dale power resistor for HV Glitch use...any idea what that part number was. I've just been searching through the Mouser Catalog, but can't seem to locate them. I'm planning on a 2500 VDC supply with 40 uf of C, to run a single 4CX800. Any advice re the above gratefuuly accepted. 73 Glenn VK4TZL
