[R-390] Need R-390A Iron Core Slug

[Flowertime01 at wmconnect.com]

Charlie,

We though all the R390/A RF deck RF octave slugs (18ea) were the same. The 
RF deck variable IF slugs (6ea) were another flavor.

Under that bit of slug stuck in the tube is the screw that lets the RF can 
be released from the deck. Oh un lucky is your stars this week.

Start easy and progress to destructive tactics as required to complete the 
repair.

Remove the slug rack to get it out of the way. 

Turn the receiver on its side or up side down and blow compressed air into 
the tube to "flick" the core out of the tube. May or may not work well.

If your air compressor allows you may consider a small vacuum line to suck 
an attachment to the slug and pick it out that way. You mite try a solder 
sucker bulb and small hose to pick the slug out that way.

Pull the RF deck and identify the very small bolt used to hold that can in 
place.
Use a small cut off wheel to slot the base of that screw. Use a screw 
driver to get the screw loose and started back out into the slug tube. Glue a 
small stick to the screw to finish unscrewing the screw into the slug tube. 
Then you can unplug the RF can from the RF deck and just replace the whole can 
and slug if you still cannot get the slug out of the tube or the tube is 
damaged so you cannot use it.


Place a very small amount of super glue on the end of a cut off very small 
match stick. Let it almost dry. Place the tip of glue against the slug being 
careful not to glue the stick to the side of the tube. Let the glue dry and 
extract the slug.

You can push the tabs on the side of the RF can in with force. This will 
let the cover come off the RF can. You can destructively or gently remove the 
core tube from the structure. You can then remove the screw that holds the 
RF can structure to the deck. Then replace the whole can and slug. RF cans 
are more selective than RF slugs. Each of the front 6 cans are different. 
While the second and third can of each octave are the same.

Back when you just pealed the can open with a hammer and sharpened 
screwdriver to act as a chisel. Ripped the guts out with some long nose pliers. 
Removed the retaining screw to get the last of the can out of the way. Put in a 
new can and slug. Tuned it all up and still went home on time. This implies 
spare parts were in the room next door.
