Reel deep thoughts...
Daniel, Ethan, Dave, thanks for the info and encouragement!
Ethan,
It is a two-wire plug...any way to still test that then...or am I correct that since it is a two-wire plug there is no protective ground?
I don't have an analog scope...I have PC software though, which is certainly not as good. I have a good DMM though (sensitive, high refresh rate). Would it be better to check for that DC ripple measuring AC with a good DMM, or use the software scope? If I use the DMM do I just set it to an autoranging AC function and measure across each conductor to ground (chassis)?
Thanks so much for the step-wise advice on checking the power supply's viability. I will do just that.
For the light-bulb load-test...So I could just take any light bulb and, given the wattage rating of the bulb, and measuring the resistance of the bulb using my DMM calculate the load right?? So in that way I could find appropriate loads for each supply circuit in the PSU right?? I have another DMM which will do data logging to PC. Could I then conceivably connect the load to the circuit and connect the DMM in parallel and log the voltage output to confirm stability over time?
Dave,
I would be VERY interested in information that would allow a reverse engineering of the PSU umbilical cable. If you have info as to where it might be possible to get the connectors and hoods, as well as the ability to spec the cable, I think that would be tremendous info to have up here on the forum. Actually I could probably get the cable spec info from Tascam engineering...cross that bridge if we come to it...If I end up needing to build the cable, I could do a couple more while I'm at it y'know?
I'm going to get in touch with the guy that has the PSU in the next 24 hours to arrange the transfer and inquire again about the cable.
Dave, is there any way you could get a good picture of one of the umbilical cables and the connector? It might help. The guy that has the PSU is not a technical person, and I'm not sure he knows what he is looking for...
Ethan,
If you are paranoid now would be a good time to test its protective ground. Take a meter set for the 200/250 AC volt range and touch one end to the PS case metal and the other to a safety ground (the screw on an outlet). There should be no voltage. (You could plug it into a GFI outlet in the bathroom or kitchen to do the same thing) I am assuming that this is a 3 wire plug but I cold be wrong here.
