R390A Solid State Conversion Video #1

R390A Solid State Conversion - video no. 1 There are a lot of details to show in this conversion project. I will make future videos showing more details. Sorry, I forgot to demonstrate SSB but it works perfectly well. I'll do it in the next one.
Since the video was made I have corrected the AVC overload on strong AM signals and the Noise Limiter now works. The balanced line audio output is still low but usable with the switch in the -10 (max) position. I have now declared the project a success.
