RA 6790/GM
                                Restoration Disaster
Did I get your attention?
Okay, so it's not really a disaster, unless  you are a purist, a traditionalist, or one of
those collectors who think that any collectible should be kept as stock-standard as the
day it left the factory in order to have any value. Most all collectors are that way, and
rightfully so.

None Dare Call It "Heresy"
But I'm not a collector. I'm more of a gatherer. I'm also a communications product
designer with more than 40 years in the business, so this may be more of an acquired
disease than a sudden flash of malcontent, or OCD. For now, let's call it a "passion."
Anyhow, my line of thinking, reasoning, logic and rationalization all lead my passion to
equipment that I like, that I want to use, and that I want to keep - equipment that is
perfect for me - perfect; the exact way I want it.

Imagine that you could design the perfect sports car - in your head - and then be able
to build it in your basement. Cool. Huh? Maybe design and build the perfect house ...
boat, private airplane? Okay, you get the idea.

So if you still think it's heresy, don't hate me, just quietly go away, because it ain't
gonna get any better. Besides, there's a lot of these things still around, and that's good
news. Bang for the buck, this top of the line receiver is really hard to beat.
Here's where we start; the original panel, although not so visible here, it's pretty well dinged and scratched. I doubt that there would be spousal approval for it in the family room. Next to it
is a cad drawing in preparation for a nice thick chunk of aluminum waiting for me at the milling machine, since I originally wanted to make my own new panel and just refinish this old one.
But strategies and tactics are often mutually exclusive. Thankfully, I was able to locate an orphan panel, so no further Racals were injured in the making of this saga.
Standard panel, but black.
Standard panel, but added RF Gain control.
Added dual Fault indicators and modified graphics.
Here's how to make the "Fault" and "Pass"
lights switch with simple diode logic
A trim pot added to the RF Gain control to improve rotational linearity.
Combiner for the added RF Gain control.

May add Transorb, MOV, gas tube, 30 MHz
hash cap, transient diodes, 20K bleeder
resistor, as needed.
The raw painted panel (powder coat) and with decals applied.
From This ...                          ... To This
Finished and in service.
