a continuation of DIY TT bearing...But now Tonearms!

That's a good idea - however, the arm has moved on a little in the last year and a half.

I'm still using it though.

The arm wires are still those from the autochanger, and go from the top of the arm above the pivot in an 'n' shape to the plinth, where it attaches directly to the phono lead. That runs to the amp as normal. The phono stage shown there has been consigned to the shelf, awaiting, in all probability, parts scavenging and disposal.

The deck, VHS head drum and the 'headshell' coin are connected together and earthed via a separate wire to the amp. I get no hum at all - just the whooshing noise of the phono stage.

I have re-mounted the armboard to move the pivot a bit closer to the spindle, to improve the alignment of the cartridge.

I also added an antiskate mechanism - just a piece of thread round the drum, over a wire hook and down to a weight (experimentally decided as needing to be 2 drawing pins).

I will put some more photos up at some point but being in the middle of exams doesn't leave much free time.

EDIT - I love your signature, EC8010.

Blutak is great for fine adjustment of bias force. I have a beautifully machined hollow aluminium weight and just vary the amount of Blutak inside.
