[Tigers] Motorola radio restoration

[awtiger at cox.net]

Hey, guys:

I'm now deep into the electrical restoration of my Tiger, as in installing a complete harness from British Wiring.  I've got all the wiring out of the car at this point and am taking care of a few other items that need attention under the dash before it all goes back in, and one of those items is my radio.  I have a LAT-72 Motorola radio kit in my car that has never worked.  The reason it has never worked (and I found out the hard way...) is because the radio itself is a positive ground unit out of an earlier Alpine.  Unfortunately, when you hook up a positive ground radio in your Tiger without realizing it's a positive ground unit, all you get after a few seconds of music is "sizzle sizzle," and then nothing.  I've been told by folks before that the ground orientation on a radio can easily be switched, so here's my question...do any of you guys know where I might be able to send this radio to have that done and then have it repaired?  I'm not looking for a high-quality audio experience here; I just want it to work and play over the single speaker provided with the LAT-72 kit.  Can anyone point me in the right direction?

Thanks,
Andy Walker
