IPA-5280-1 Power supply, Works 100% 5 outputs paired +9 and -9 Volts DC (Input AC line 100 to 135 Volts)It feeds up to 5 instruments of the 52xx Heathkit line of profucts. (Blue series)Updated to use modern connectors (Bi-voltage)Connectors: 4 of 5 are modernized, the old model (Amphenol) breaks too easily. I ship ONLY to Canada or the continental states of the USA. If you buy more than one instrument from my list, ask for a group shipment. Thank you for watching

Set of 3 instruments (IG-5282 Audio generator, IG-5280 RF generator, IM-5284 Multimeter with large galvanometer and its special Heathkit power supply IPA-5280-1) is sold into one ensemble ONLY. (Not sold separately) IM-5284: Multimeter, These items have been improved, especially, they have pilot lamps for each function as the original items were consuming internal (standard 9 volts) batteries at the speed of light. With bright LED lights, you cannot forget to switch them off when you have finished. Anyway, they NOW are working with the specific line 120 volts Heathkit added for these instruments., batteries are NOT needed any more. (but you can still connect standard batteries if you like to work independently..Voltmeter AC and DC up to 1,000 volts, Ammeter DC measurement up to 1,000 mAOhmmeter X1, X100, X10K and X1Mohms IG-5280 RF generator.310Khz to 110 Mhz plus harmonics X2 (220 Mhz) in 5 bandsOutput 100mV Internal modulation 1000Hz, AF output 2.0 Volts, IG-5282 Audio frequency generator:10 Hz to 100 kHz in 4 ranges, Sinus waves 0-3 volts, Square signal 0 to 3 Volts, separate outputs IPA-5280-1 Power supply, 5 outputs paired +9 and -9 Volts DC (Input AC line 100 to 135 Volts)It feeds up to 5 instruments of the 52xx Heathkit line of profucts.Updated to use modern connectors (Bi-voltage) Each item is guaranteed in terms of measurement (Voltage) and frequency and fits with the manufacturers specifications. Returnable within 2 weeks if any does not fit with the description above, It is a very good set of instruments working OK. (and still in use). I ship ONLY to Canada or the continental states of the USA. Shippings paid by the buyer. (Via EBay) Thank you for watching GUARANTEED 2 weeks, returns accepted if not in conformity with the description .I only have one set like this one. Schematics (paper copies) are attached for each instruments.
