Thanks! I can't understand how I missed it. Jon has a fantastic site, dedicated to identification and preservation.

Greg, 
To get the investigation started, compare the two sams photofacts in downloads under tuner and preamp schematic. A 7001-20 appears to be an earlier version of the MPX adapter chassis.
They are different in that the three tube unit has an dual triode audio output amp, while the two tube version has an input signal amp before the cathode follower, a 12AT7 triode used on both types.
Instead of a 6AB4 and 12AT7 in addition to the 6EU7, the two tube version uses a 6EA8 for 19KC amp and doubler, like Zenith and RCA do. ]

The differences are numerous but the good news is the 12-pin Molex plugs appear to be identical on both. How interesting it would be to swap out and compare :-\

I will get a better shot of the interconnect diagram in my cabinet when I can but the actual molex plugs are the same. The MPX plugs in between the amp and tuner.

I made a drawing when I pulled it apart. Not as complex as my Motorola SK112 with the FM adapter and verbaphonic.
That beast was a challenge to my aging memory, so I used electrician's Brady number tags to match all the Molex, RCA and spade lugs.

Fisher, RCA and Zenith consoles are a lot simpler in this regard but damn, aren't they are all fun?

I have a three-tube MPX adapter in a 1ST659, in the 1962 catalog "Normandy Provincial".

I'm checking for a picture in my file. The console (everything apart but restored) is buried in my attic as I work on a room for it

Well spotted Ken!

What a remarkable Windsor, I always wondered what the first one looks like. Thanks Paul

Welcome to the site, Tom. That looks like a 1962. I have a similar model named Normandy in "provincial fruitwood". Its been recapped and I have not even put it all back together yet. Too many projects but its one of my favorites.

Yours probably has a tube amplifier and tube tuner.

 See what the chassis numbers are and I bet all the needed information is here in "downloads" Tuner-preamp might be 79-01 etc and amp is 93-00 etc. It may have an FM multiplex adapter 3-tube chassis also. The record player is the best and easiest to restore IMHO.

Pilot was one of the interesting pioneer post-war manufacturers and I would rescue it also.

I got a Pilot 12" table model TV on CL a few years ago, it was a 1949 and has an FM tuner.

Consolettes / Re: General Electric and porta-fi

These wall mounted units had the same tube tuner and amp, later transistors.  I think the porta fi was only offered with an SS amplifier

These pictures are of one I missed out on the local craigslist.

Its not good to have a year since the last post in a forum but this is one is asking if any one has a GE in that wall-mounted cabinet with either a Garrard or GE changer.

I recall their early solid state amps mated to tube tuners on some. 16 ohm speakers ?

Magnificent Magnavox / Re: Are the W801 and the W711 interchangeable?
« on: October 04, 2017, 01:10:51 PM »
I was wondering how to respond just before Electra 225 found a good thread for your player's issue. I was not familiar with the W701, only the W600 series.
Picture is a W801 I restored and sold the console, it used a very small EV cartridge that used a fixed diamond stylus (cant flip to 3 mil 78).

One thing with all these changers is you can't switch between 33 and 45 unless its off.

Try to work on the W801 Micromatic if you can. Those parts on the W801 were pretty standard and even if you do need an idler pulley, it will be a very reliable and fun player when the initial issue is fixed.

Yes, that Pilot may be an FM-200, a 22-tube set with a separate amp chassis, two speakers and push-pull 6L6 output tubes.

I looked at a website I use to visually identify models, radioatticarchives. A number of Pilot radios appeared with only one console, the FM-12. Then I checked another excellent site, NostalgiaAir, which has resources in the form of Rider's Schematics. The FM200 shows by its circuits that its quite a high-end unit.

I opened it up and took a few pictures. Checking ebay, this was not a top of line model with separate amp but all in one receiver chassis very similar to a mid-level Magnavox Astrosonic. The unique Cartesian AM - FM dial was used on the more expensive models.

On another note, I got an address from an ebay item of 1905 Armacost Ave in Los Angeles. Using streetside, the low brick building is now a charter school, so it was too solid to demolish but in the 1950s(?) it was pretty modern-cool.

I recall Packard Bell TV's as prizes on "the price is right game show". But like a Curtis Mathes, I never saw one in person.

Other Solid State Console Brands / Packard Bell RPC-66

I'm working on this solid state console that probably needs caps among other items. The voice of music changer is branded PB also but uses an odd cart.

Has anyone here worked on a PB before. I have a Sams 905 for the RPC-56, hoping its close. Pictures once I open it up.

I think this model appeared in multiple years, starting 1970.
By the look of the TV controls and the Astro-sonic chassis, and not finding in this site's downloads, this may have been a mid-1971. The model numbers can be confusing but the 2-prefix seems to denote a hold-over offering of "last seasons model at a lower price". A 1972 catalog or mid-season 1971 brochure probably nails it.

If the Astrosonic chassis slides into a combined wiring connector, that is 1971 and later. That easy - slide is not an improvement but a new place for issues to develop.
I had to hard-wire the phono pickup cable on one I restored, but that slide-in chassis had a pushbuttons instead of a rotary switch like yours. That micromatic record changer on yours is a good one and easy to restore.

The Magnavox TV chassis may have a postage stamp sized white tag on it listing both chassis number example T940, T950 etc and the build date, like 02/71. They were mediocre picture-wise compared to a Zenith of the same year, but not too troublesome.
