Gentlemen...

Just signed up for the Reflector this afternoon...after a very long time 
away...

Noted comments re the R391s... I have three of these beauties..and two 
power supplies...

Both supplies have the very large selenium rectifiers....

Their status...Rcvrs are in excellent cosmetic condx....and were 
operational re electronics and one motor tuner was good when I got it...

The power supplies are in good physical condx..with one working when I 
purchased it several years ago...the second ps...was found at Cleveland, 
Oh hamfest...and was tinkered with...but with all parts...it was used 
... apparently for a supply for other projects...

Current status...pending some bench time...to get time on line...

Will be interested in any info...history....on these excellent 
rcvrs...all have 26Z5s at this time..

I can dig out serials and serial plate info if there is interest . . . 

73,
