Heathkit EUW-15 Universal Power Supply Variable Regulated DC and 6.3 VAC
I have for sale a Heathkit EUW-15 Universal Power Supply which is excess to my needs(I have another one in use) This supply can provide variable regulated high voltage DC from 192 to 411 Volts. The current available from the HV is 100 mA. It also has a non-regulated mode which has five steps of 101/201/301/403/505(measured) It also has a 6.3 VAC output at 3 Amps. This an ideal bench supply for testing smaller tube projects and other experimentation. This unit is missing its rubber feet and it has one incorrect knob. I have listed this as 18 pounds for shipping calculation. If the actual shipping cost is less than eBay's calculation I will refund any difference. I know how to pack for survival and will.
