SOLD!Tenma 72-6180 13.8 vdc 40 amp power supply.
This little gem is only slightly larger than my icom 7300 and weighs 20 lbs!
thoroughly checked out and it is in good cosmetic and excellent electrical condition with minor scratches.
Adjustable voltage from about 5 vdc to 15 vdc.
I have made the following mods..
1.5KE 15A zener transient voltage suppressor added to d/c output
NTC 2.5D 12 amp a/c inrush current limiter (varistor)
45 ohm resistor in parallel with 110f thermostat in fan d/c B+ to ensure very quiet fan operation at low current draw plus full fan output at high current draw.
Want $120.00 plus a little help in shipping.
