{Collins} R-390A Local Gain



Hello All,

   My R-390A local gain does not go low enough.  If I turn the RF gain up all the way and the local gain all the way down, the volume is too loud.  I ohm’d out the LG pot to 2.3K.  Oddly enough, when I grounded the wiper of the pot, I still had audio output…….. 

 

Perhaps this audio “offset” is normal. I hope not.

 

 

Thanks

 

Rich
