[R-390] Unable to ZERO ADJ

[Flowertime01 at wmconnect.com]

Stan,

If the receiver is on rails and not hanging from the front panel bolts,
You can drop the front panel on the receiver in the rack.

Not recommended but then every one thinks any one can just hump
these receivers any where any day.

You can slide the receiver out far enough to get the IF band switch and BFO 
shaft extensions loose.

Also pull a wire harness screw near the local audio on the bottom side.
If it is a table mounted rack you may not be able to get to this.
With the screw out you just get a bit more free play in the wire harness.

Then slide the receiver back into the rack and remove the hardware to drop 
the front panel.

You can let the panel hang from the wire harness up side down.
You risk breaking a short wire to the front panel some where.
Watch what you do. It is repairable.

If the Zero adjust just needs the dial washer fixed or some simple cleaning 
you can do it with the receiver in the rack on the rails.

You can at least examine the problem and see if more work is needed.
