The mono console, Audrey, is capable of both an internal speaker, or, external speaker; a modern coaxial ceiling speaker is onboard the console cabinet in the lower portion.
I also use the console to drive one of the two General Electric A1-400 coaxial corner speaker; c. early 50's.
In that image, Audrey is driving the top GE corner speaker. That is the right front corner of my music room. It is an awkward corner alcove that made a really nice mono corner system area.
The cabinets are original for the speakers. The lower 1/3 of the front baffle is all perforated with what is likely 1" holes through to the inside of the cabinet.

Audrey is a sleeper build.
The Presto sits on a Mass Theory Birch Ply plinth, with multiple layers. The entire depth from the 1/16" solid copper top plate, to just above the amplifier, is the plinth within the cabinet. It is, as mentioned Mass Theory, solid leaves, bonded together, and, also suspended on a very live rubber suspension system within the plinth to isolate the TT from the cabinet body.
Even with the onboard speaker, it won't feed back.

Layers and, testing the rubber suspension in various configurations:

Mass theory, minimal removal of plinth stock material, with well supported bearing well hole:

Finished and mounted:

the lower small black shelf, ^, is the mounting shelf base for the HK Prelude integrated mono tube amp; removed in the pic:
 
Im slowly getting my 401 up and running again. Today i borrowed my brother-in-law's jigsaw, it was the first time ive ever used one and i think i didnt do too bad. I even managed to get the hole for the arm cut correctly this time!

I need to order some decent plywood over the weekend and can then get the plinth done and dusted, hopefully by next weekend when i can get started on enclosures for my speakers!

I just looked up these pioneers and wow! I think they might be easier on the eye than a 401! Probably a fraction of the price too...must resist urge to buy one!....
Mine had a bad "run" capacitor in the power supply. It would run for about 30sec., then stop. I would start it again, and in half time, woud stop. By the third try, nothing. So, I replaced the capacitor, and it has run perfectly.
Because of the bad capacitor, it was sold as not-working. I got it for a song.
It is a really nice deck, and runs silently.

There are different versions of the PL-x series. Most are stamped metal top plates, and lighter platters. The PL-7e has a cast alum/white metal top plate.
The underside has a nice driveline.
The capacitor board is my replacement rigging, to replace the multi-layer cap that was bad.

this is the underside of the cast top plate:

Im a bit behind with my plinth project for my garrard 401, it should have been done weeks ago!

Does anyone have an opinion about materials? I was thinking about using just birch plywood but ive read that some people add a layer of two of mdf to the mix. Or i might be able to get hold of some slate...
 
This followed me home today.

Rek-O-Kut TR43H. Used as a cutting deck, apparently.

This thing is solid. Very solid. The motor looks better suited for running a washing machine than for spinning a platter. The idler wheels looks to be in good condition, at the moment, it only seems to need a ball bearing in the bearing shaft.

Nice ROK. :)

I love the sound of my idler tables. :)

I had to make the decision to stop spending as things have been getting out of hand lately. However my L70 has needed new bearing bushes for a while and I really would have liked a fancy new bearing for it so I thought I'd try my hand at making my own but using the old spindle as I'm certain that would stretch my talents just a bit much. Anyway here's the result. It's not perfect but it's quiet and I'm pleased with it.image.jpegimage.jpegimage.jpeg

Thank you kindly Redboy. Unfortunately I have other things to attend to atm so progress is a bit slow I'm afraid.
