TD125 Recap Help

dodog · 2013-10-15T14:16:07+00:00

I have a Thorens TD125 (MKI), with crusty old caps. It powers and spins but it won't hold speed well. A recap is in order (yes, contacts need to be cleaned as well). However, I need a little bit of help on the cap selection. Here is the board layout for the MKI (borrowed from vinylengine): However, this is what I have: For comparison, this is what JonL had for his MKI and it looks quite different (pic taken from JonL's post at: http://www.audiokarma.org/forums/showthread.php?t=263801&highlight=thorens+td125+cap , cropped and flipped for better orientation): As you can see, past C9 on the board, things are pretty different. I have jumpers where he has resistors, spaces where he has caps, etc. I'm pretty sure everything is stock on this table and board, I think I might just have a really early version of the table. I wouldn't be shocked if they altered the layout through the years. I know that the first 6 caps are electrolytic, axial leads, but what should I replace them with? For example, if I use Nichicon, which series should I use? Do the trimpots need to be cleaned with Deoxit? I know that they're used to set the voltages, per the service manual, but unsure what they are exactly. Are they just a variable resistor? Do they have contacts that need cleaning?

I'd like to know too. I've got to open mine up to do some mechanical work and thought I'd do a re-cap at the same time. My strobe takes awhile to stabilize as well, but I thought this was normal?
