[R-390] Audio Gain Pots?

[Jacques Fortin]

Sorry to rain on the parade, but I just checked the pots I kept from two
R390A Moto "junk" units, and 2 are audio taper, the 2 others are linear.
Could it be that the Local Audio ones are audio taper and the line output
ones linear ?
The linear ones have CTS P/N 318K146 and the audio taper ones have 380 0588
009.
I have to check what's in my Motorola '56 now....

Regards to all,

And you definitely do *not* want to replace them with linear pots, or you
will be the next one asking why the audio is screaming loud even with the
pot turned way down.
