Well, the 1600+ sq ft of basement is counted as unfinished space on the tax record, so adding sheet rock really wasn't in the plans to start with. Plus as Tom mentions, I think leaving the insulation exposed helps deaden the room. Besides, it's a Man Cave. It has a commode and pro popcorn maker, but no TP, Alcohol sanitizer and paper towels, but no sink. It was designed to be unattractive to members of the fairer sex.

Anyway, back to the original topic. I've looked up the N500F here, but I don't have any 15067s, nor does this have a schematic. Is Steve Schell still around? He apparently has a schematic for an early N500A, which I'm guessing is close to what I want. Anyone else know a source for a similar late 40's early 50's N500?

Better get some burlap and I wonder if that would even help. Fiberglass is as nasty as it's name implies. I have a hard time understanding why it isn't banned along with asbestos. The problem with fabric coverings is that they burn like gasoline.

You looked at least a half dozen or so in the eyes while you were here. Lemmee know if you go that route, i can hook you up.

Ebay, where they average around 500 a pop for singles. You'll either have the good fortune of crossing paths with one in the wild(which could take way too long), or build a facsimile.

Aren't those early networks a "series" topology?

Considering the resources available to you, why don't you have one built yet?

I understand some people have a nasty intolerance for glass. I remain thankful that i'm not one of them, as it's the best speaker damping material and home insulation available to mortal men. It's also great for controlling room acoustics.
