I am looking for a tenma power supply, model 72-6180, manual, service manual and tips....secured one at a swap meet and it works 100 percent but can't seem to find any info on line....looking for a schematic for the same and if a ovp(crowbar) circuit is advisable for same.
I cannot find anyplace online for this old power supply so am hoping someone has something out there...thanks de wb7tdg
