Steve Morse is a genius and Ultravox ain't bad either!

Oh my that's a treat. Thanks for sharing!

It seems 90% of the time the reason a TD125 stops working is one of the two capacitors under the bracket on the board fails. The ones on this unit were way out of spec.

It's an early arm as shown..

Thanks! I was wondering if the MIDI connector was the same.

I really appreciate the discussion and insights! My tonearm does not have a din on the base, just wires coming out, so my thought is to go from the tonearm to a din mounted on the plinth. The wires are tiny and should not affect the suspension.

Jim there are five tiny wires coming out of the tonearm. l/r +, l/r -, and ground. I am thinking it would be nice to mount amale 5 din plug on the back of the unit, and then connect the preamp via a cable with a female 5 pin din plug on one end, and rca's and ground on the other (preamp) end...

Thanks Jim! Here is the protractor I am using for this tonearm. I decided to go with Lofgren B setup. I used https://alignmentprotractor.com/2-point-protractor-generator to setup the protractor. Now I'm going to make a mounting plate for the tonearm, I hope to make it before the weekend. I'm...

Hey Professor! How you been?

In case anyone needs mounting specs...

just looking around

oh yeah... lol

After removing the old tonearm and armboard, I decided I would replace the old armboard since I was going to need to redrill in order to mount the new arm. I decided to go with Leopard wood. I just finished making the blanks. I made and extra one since I already had all the tools and such out. I...

Next up was the oscillation mirror. I discovered it had fallen out of it's designated mounting spot, so I tore in and remounted it. In the photo below you can see where an old rubber isolation pad had disintegrated. I cleaned all that crusty white adhesive and placed the pad. The second photo...

I didn't take any pictures of disassembling the unit, but there's nothing too complicated about it. These units are well known for malfunctioning due to bad motor control capacitors. I tested the unit, and everything checked out, but I decided to go ahead and replace the troublesome caps anyway...

So the overall plan is to install an early Micro Seiki MA-77 MkI tonearm with subweight, repair the oscillator mirror, recap the board, install new cables, replace the armboard, and clean up the plinth and dust cover. It will need new feet as well. I will be replacing the original three button...

It somewhat reminds me of a Phase Linear. Good bones, but lots of room to do good things to it. I'm pretty well down the path, and dropping back to share pictures while I wait for some parts.

I'm reworking a Thorens TD-125 MKII turntable I recently picked up. The plinth, platter and mechanical were in pretty good shape. It had an odd tonearm with a SDT cartridge. The oscillation window wasn't right, the needle was missing from the cartridge, and the belt was probably original from...

Just curious. The speaker protect board has a Zobel network. Does the White Oak board have one also? And would that be a problem? I remember removing the zobel from Don's speaker protection board on a couple of 400 rebuilds.
