[R-390] SS conversions for R390A, SP 600 and other BA receivers

[Perry Sandeen]

Yo Bubba Dudes,
A long term project in my mind was if it would be possible and practical to SS BA receivers?
I found two R390A conversions on Utube by Charles Smith KV4JT  (charlessmi1 at gmail.com.
The two videos show him demonstrating two R390A receivers one tube and the other SS side by side.
He notes that IIRC there still is a problem getting the meter circuit properly.
He sells a 20 or so page manual with 5 11 X 17 detailed schematics.  They are excellent and he probably made 10 cents an hour for his work
I'm very interested in the SP 600 conversion as it removes 12 pounds of weight from the receiver and one can get at most of the innards easily.
There may be things that can be improved. 

BUT before some list demented cretin nit-picks and complains remember he made the circuits for the tube substitutions, made it work and most important of all MADE IT AVAILABLE FOR ALL at a most modest cost.
If you're interested in going this route check out his Utube videos.
I bought ski's for the "A", SP 600, and SX100.
Regards,
Perrier
