There are a few ways of achieving it. I went under the main PCB and soldered direct to the track for the second +21V feed near C110 as I didn't want to drill any holes. I also mounted the two tertiary regulators component-side up, unlike Paul, as I found it easier to guide the silver wiring that way. I also star earthed everything except the +5V supply across D301 which Paul identified as critical for a short path.

Well i've cut the tracks and removed all the components from the PCB, tonight i'm in Salford, going to some lectures about biomechanics :eek: so no techie development. I'll be planning where and how to drill the holes later this week and also getting my head around star earthing and a few other bits and pieces ;) I cant really got much further as I need some teflon for the silver i'm using :( thanks for the encouragement and recommendations guys

Teflon arrived today :eyebrows: I have a horrid feeling its not the correct diameter :steam: should commence soldering tonight..... :eyebrows::eyebrows:
Right everthing has been soldered together and plumbed in! MAN what a journey :) Just got to hook up the power supply and change to 27V. Then we can start spinning some vinyl again. All I can say is I'm glad I dont have to do this every day for a job. :beer:
There is a point when you wonder if it'll ever turn a record again :)
I've just added a quick piccie of the inner workings! I have a really sneaky suspicion that it wont turn anything tomorrow, I just keep thinking I've missed something or the soldering isnt up to scratch :(
Where's the red incoming going to (from the braided DC cable)? Shouldn't it be feeding the TDR-12?
Also, you really want to remove that plastic motor cover for best sound quality.
Red lead is the only bit that I haven't fitted yet, I goes to terminal 5 or 6 on the tr21 module, it's in the instructions, I just had enough last night and I decided to call it a day, the old eyes wear closing which isn't a good sign :eek:
It's a good idea to put the coil cover on when you are doing this sort of work.Quote:

Yes, agreed Mike. I was only concerned in case it was still fixed in place.
