[R-390] Brought Home a R-390 Today (along With a Viking I)

[Gary Harmon]

R-390/URR
Collins s/n 2941
Order 14214-PH-51-93
MWO 11-5820-294-35/1
MFP Nov 1956  ?
 
Homemade top cover, no bottom cover, has meters and AC cable, R-390A manual
copy
 
Note on PS says, "Remove tubes, modified for solid state rectifiers"
 
Note on top cover says, " PS problems - need tubes; 6082 (2), 5651 (2),
maybe 26Z5W (2).
The 26Z5Ws were modified for solid state diodes.  Need to remove tubes if
using the diodes."
 
Radio is blowing the 3/8 HV fuse.  This action probably accounts for the PS
problem note.
 
Receiver is in excellent condition.  No scratches or mars on the front panel
but several knobs could use redoing.  Gears look clean, no gook.
 
Things to look for?  Leave solid state modification?  Other mods to do or
look for?  Site for R-390 restoration?
