Thanks for the info and link.

In my shop, I’ve got some nice chopsticks, one set hardwood, another set plastic, if I can find them.

And a grinder, and lots of other sharp weapons of destruction.

I know where to make the connections, evicently going for .4 or a bit less.

Multi-meter on what setting????

I'm betting it changes nothing, but, I'm gonna do it, just to find out.

My JSE's are at my son's house, I have gone back to my vintage drivers in a custom Rosewood Enclosure. (3 way: horn tweeter, horn mid, 15" woofer, from 1958) 

My setup, those speakers, and TT with 3 arms can be seen in the photos of this LP listing on eBay. The Reel to Reel is horizontal, under a tray of plants. The tray relocates onto the TT when playing Tapes, back for LP's

I wanted more power for the JSE's, and a friend gave me a SS McIntosh MC2250 and C28 he wasn't using. Damn good no doubt, Amp, full on, dead quiet, tested 305 wpc by McIntosh, it simply wasn't there, just did it's job, perfectly.

I did not like the phono stage in the C28. As I said, I just got lucky finding the article about the mx110z, then found one, the best purchase ever.

When I went back to my horn speakers, hardly any power needed, it was back to tubes, always my preference.

Simply put, this setup I have now gives me and the wifey, (and my friends with masks) a great deal of listening pleasure, especially having rediscovered LP's and investing in improved TT setup. 

The Turntable, 3 tonearms, developed piece by piece, finished very well, way beyond what I started out to do (single long arm).

I don't have a lot of space, 3 arms on 1 deck, select via SUT, mix long arm MC, normal arm MM, compact arm MONO, change instantly in a listening session is absolutely wonderful.

That preamp's tuner and phono stage are simply wonderful.

you can find a 500c, or an 800c on eBay, do you really want AM? that's the only difference between the 500C and the 800C

here's one way to save a lot of $

Check Mapleshade Audio. If they are still in business, they used to sell re-conditioned vintage tube gear, specializing in Fisher stuff.  You pay a little more, but you get a completely rebuilt unit probably with a warrantee.  Otherwise, if you are not a skilled DIYer, caveat emptor when it comes to very old tube amplifiers. They can be fun to fix, but they can also be a pain in the arse.  I would NOT buy off eBay unless the seller is well known and within the USA (for buyers who live in USA).  You want to have some recourse if there are insurmountable problems.

For my own curiosity, I checked out Mapleshade.  Yes, they are still in business, but no they don't say anything about restored vintage Fisher gear on their website.  I would still call them if you are interested.  Pierre Sprey who is one of the principles of Mapleshade is a great and brilliant guy.
