I'm about ready to take my Dremmel Tool out and cut my C603 and C606 power
supply filter caps open to RECAP them from my "cap kit".  If I screw them up
on my first go round, how hard is it to find replacement cores to try it all
over again if I fail the first time?  Are they available?  It would make me
feel a lot better knowing they are not impossible to locate or I had spares
if I did screw them up.  Anybody have any units bad or good available?

never seen any like this before.  But then, I am new to R-390A restoration).

I have looked into the problem of replacing the filter cans C603 and C606. 
The best way I have found is to buy several 8-pin Octal Base Plugs available 
from many sources. I bought some aluminum tubing that was a close fit to the 
Octal Plugs and cut a few lengths equal to the originals. The newer 
late-manufacture HV Electrolytics will easily fit inside the aluminum cylinders. After 
wiring up the caps the aluminum tubes can be glued to the Octal Base and then put a 
nice looking end cap or hole plug on the open end of the tubes to seal them 
up. I have found the 8-pin Octal plugs grip pretty tight when plugged into the 
octal sockets with the new lighter-weight cans so there is no need to use the 
clamps around the cans. You have to really tug on them to pull them out. The 
original heavy filter cans only had 4 pins and didn't hold very tight in the 
sockets and needed the clamps to stay put. The end result is a nice-looking pair 
of plug in caps that can be easily changed out if ever needed. 73 Todd
