[R-390] OT: Scratchy speaker

[Scott, Barry (Clyde B)]

Cool!  Tears I can fix; voice coils scare me.

I'll be sure to remind you.  Thanks so much!

FYI #III -

Checked one of the parts rigs earlier, do indeed have the bracket you 
need. Just so happens it's attached to a speaker. Speaker looks fine 
except for a small (maybe 1/2"?) easily-accessible tear you'd need to 
fix. Sucker has a buncha wires going down through the chassis though, so 
removing it properly will require some time (in short supply ATM).

Drop me your address when you can and remind me maybe the second week in 
September if you haven't heard back from me. Took me a coupla months to 
send a #80 tube to Al Parker, but I finally found the time!

BTW, T.O.s are really great little receivers, certainly on par with the 
R-390 series for enjoyment factor. Amazing sound, too!
