I recently bought a Cobra 139 XLR at a garage sale for $15. The guy

(no extra switches, no missing/stripped out screws or knobs, no holes in

the case, etc...I've always been told to STAY AWAY from those radios

unless you know the person who did it and you know they know what

they're doing)and I've seen the "it lights up, but I don't know what's

wrong with it" ones go on eBay for $40+, so I bought it. I took it home,

and found that the radio receives GREAT (TONS of skip with an indoor

antenna!!) but no transmit (meters dim and deflect momentarily, but no

"dead key" even with whistling) No power out indicated on my watt meter..

Is there an easy and/or cheap fix for this? Can you still find the

needed part(s) for this 35+/- year old radio?



The components are all surface mount.

If you can read the schematic's and if you can solder and if you have

the proper tools to do the proper measurements - you can repair it

yourself.

The problem is with a $15 radio - you probably aren't going to spend

$50.00 to repair it...

I have a friend that I could borrow a multimeter (and maybe a soldering iron) from, I'm just worried how much the parts could cost, and if IS the finals (I'm thinking most likely) can they be found?? For a 35 +/- year old radio, it's in pretty good shape otherwise.
