[Hallicrafters] SR-150 Transmit Audio

[Laurance Brungardt]

Hi Guys,
 
My rock solid SR-150 developed a problem last night, no transmit audio. The PTT works fine, the rig still has full power out in the tune position. I've done basic trouble shooting and looked at all the usual suspects but no luck. I was using it at the time and it just went from working flawlessly to not working, no pops bangs or smells. If anyone has had a similar problem and could give me a pointer as where to look I would really appriciate the help.
 
Thanks,
