Sorry, I thought you were thinking there was 8v wiring from the Yaesu since that's he had.
I didn't think any of the four pin radios have any 8v feed to the mics, that's what I was meaning.
Bad thing about typing, sometimes it may seem there's some bad feelings or issue implied, but far from it from me. These are very interesting threads.
I was just trying to keep it simple for him. But since he doesn't solder, I don't know what to say, yikes.
Being a cb, I'm not sure even w2ihy will build him a cable.
Eastside, I can't tell you enough how easy it is to learn to solder, at least good enough for something like this you're doing. Best time to learn is right now! 
I'll keep my comments off the audio stuff.
Robb, a side point, have you ever talked to a W9FAM? Look him up on QRZ.
Very interesting man. He's 90 now, owns two radio stations, one in St Louis and one in
Kokomo Indiana.
He dissected a Icom 7800 and disabled all the inboard audio and has his home studio with about, I believe he told me, $17,000 worth of equipment going into it now.
Probably steeling from work. 
i had to laugh as he's using a Neumann. I asked him if it was the 87U and just gasped, said that was too expensive for him. His was only $1000 mic,
I about rolled out of my chair laughing at that one. I guess it was late, and the timing was like Bud and Lou of times gone by.
