[R-390] leftover hardware

[Craig C Heaton]

Brian, et all:

If it's an "A", I believe three screws are used to hold the crystal deck in
place, front.

As someone who had to disassemble and reassemble lots of stuff, work with
aircraft mechanics, and others; we all developed a method of organization.
As each piece is removed, set the fasteners with that piece or place them
back into the holes from which they came. That way there aren't too many
parts n' pieces left over. 

Putting everything into one big brown paper bag, shaking well until mixed is
not a good option for most of us. I had to work with an ex Continental
(aircraft I/E) who would remove ten screws and only replace five. His
thinking was it would take less time to fix the next time. 

The two R-390A's in my shack were missing fasteners, must have been the same
I/E. 

Many years ago, I was in Atlanta, GA for some training on a new model
(un-named). We worked in teams of two and it was sure fun to put some extra
part n' pieces on someone else's table!

Please don't laugh.  I've got the rx back together and have a few 6-32
screws and washers left over.

This after R&R the PTO, IF and RF decks.

Here's a list of what I know IS installed:

The two that are reached through holes in the front panel of the RF deck,
one above the other, in the middle.

The three that go in the right side of the RF deck, through the chassis
sideplates.

Two on the bottom left side of the RF deck, accessible through the big hole
in the side of the audio deck.

Two on the front of the RF deck that hold the crystal deck in.

None of these are captive 8-32's.  They're all accounted for.

One is absent from the cable clamp on the pto, but that's a known.

Which still leaves me a couople left over and NO visible holes to stick them
in.

Is there a listing somewhere of where all the green screws go in this radio?

PS the radio is working fine and the 30dB drop on audio is there when tested
modulation-on/off.
