SB-104A

[Richard Parent]

Can some one tell me how to retrieve info on Modifications and or factory
improvements to the SB-104A, if they exsist. I recently saw some go over the
list for the SB-101. I have both in running order.

On the SB-104A, I am trying to make the Noise Blanker work, it passes IF but
doesn't seem to NB.

Also, the Volume Level Control  doesn't shut off the audio, seems to be
over-driven to the Final Audio Amp.

Sure having fun getting both of these in shape.

The SB-101 had very little audio modulation, after chasing that around for
quite a while, finally found 10ufd cap in cathode of audio amp open, works
great now.

Hopefully I'll master this list.. thanks  rich.
