[ARC5] Advice requested...

[Kenneth G. Gordon]

Although this is a bit off topic, this group is the first one I thought 
of to ask this:

I have a Mackey Marine model 128AY receiver here, which I want to 
restore. After several years of off and on work, I have managed to 
accumlate an entire schematic, and most of the wiring diagram, in 
addition to the operating manual.

(For those interested, it is up on my website, W7EKB.COM in the Glowbugs 
sectoin, under Military.)

Although my receiver is not missing any parts (as far as I can see) the 
chassis and front panel are not in good condition, with some rust on both 
and terribly deteriorated paint on the front panel and cabinet.

And here is my request: the color is a sort of green. It is very 
difficult for me to tell exactly what shade of green, and I am hoping 
someone here can tell me what the shade is so when I refinish the thing, 
I will have a close match to the color of the original receiver.

Anyone?

Also, I find the circuit to be rather unlike any regenerative receiver I 
have so far used: it has a triode (6J5) regenerative stage, followed 
immediately by a 6SJ7 detector stage. In every regenerative receiver I 
have yet seen, the regenerative part IS the detector.

In the RCA model RBA receiver, the detector never is allowed to go into 
oscillation, and the receiver has a separate tuned heterodyne oscillator 
following the regenerative stage, but this circuit appear to be backwards 
from that one.
