I'll get to the laughing part soon.
First things first. I bought on ebay a clone; the hp100 that was marketed by everyones favorite Radio Shack. Seriously, they did have some really nice things and at one time could get just about any electronic component you'd ever want. These days it's more of that "you have questions? we have cell phones" routine. Anyway, the cans arrive without the transformer set and as you can probably imagine after checking the plugs; hey! six pins I wonder if.......oh yeah it works, fits anyway. So, Plugged in turned on kinda moment of truth....and......wait......oh no, channel imbalance, left side fine right side weak or nothing. This has happened before to me and after some research discover that failing drivers do this and it's time to retire the headset. Undeterred I immediately open the cups to check the wiring and drivers. Everything looks connected. Three wires on one side, connects and three more across the headband to the other cup. Hummmm, maybe i should listen to them now? turn on, hold to ears and.......
OK, volts are not amps and that's a good thing. At this point lesson learned and I contact the seller and explain that they don't work. Two days go by and I decide to try again. This time I notice when I try to balance the channels that the left never losses volume, could it be that the one post I'd read that said that they just plug in and ALL the other posts that say you'd need to rewire them is TRUE, AS READ ON THE INTERNET! I
OK, I have a multimeter should be simple to check continuity from speaker leads to the pin and re solder the channels properly; no. srd4 is a no go; no center pin, srd6 is a go except two blue wires, two red and one green.
Were you in my place would you rewire the spare adapter or rewire the headphones to match the adapter?
I guessing now, Green wire is bias and red and blue are channels.
I have the Realistic power schematic but it does me no good since outputs don't match pin assignments. 1 through 5 on the diagram except I need the plug codes: 12 o'clock, 3, 5, 7, 9 and center. It might be that the headphones really are defective and I don't have to refund the refund.
If anyone has the codes for an SRD-6 that would be great. Comments such as "hey D#@&a!@ there electricty in those wires" also welcome.
