I had bought this device many years ago and never really used it much because I never had batteries that were good enough to use this device on because it draw up to 10 amps and would drain a battery very quickly so I have made a battery pack for this device now ( and for inverter that I also have ) but I still have to buy a 10 amp circuit breaker for it for it be completely safe to use it
The reason why this device end up in a Radio Shack power supply case was the transistor small heat sink would get very hot to touch after a very short time and I had these power supply that I bought when they were being closed out and had a newer version of it which I did not think much of so I bought as many as I could back then I still use one of and to power small devices every so often
This device did get recapped because it had been in storage for a very long time and because it had non brand name capacitors on it
The output is 16.75 volts with no load on it and with a one amp it still maintains a 16.75 voltage ( incandescent light bulb load interesting results ) I put this device on a 12 volt li-ion battery pack that was discharged 9.75 volts but could not keep it working because I only have a 2.5 amp circuit breaker on it right now it was showing over 6 amp going to the battery pack
After I do some testing I might end up putting a 12 volt temperature controlled cooling fan over the heat sink to cool it
I will post some pictures of this when the project is completely done and I have done some testing on it when I can post the results
