[R-390] Collins R 389 PTO

[Cecil Acuff]

    I know this has been a problem for quite some time.  Several have these 
receivers that either have damaged PTO's or no PTO at all.  One recently 
sold on Ebay without a PTO.  Use to be a list members radio.  Not sure where 
the PTO went but an otherwise nice radio sits without it's PTO.

Has anybody though about sending a sample of the core mix to someone who 
makes ferrite beads etc and see about having a custom job done to make up a 
few dozen.

With what the R-389 is valued at it would seem to be a worthwhile pursuit.

Of course the core may not be the only issue.  The coil may have bit the 
dust as well when the core was shattered.  If so that's another issue all 
together.

I'd love to own one of the radio's myself...even with the PTO problem to 
take a shot at a fix.

Do have a Hammarlund SP-600-VLF...guess that will have to do...
