Nude Turntable Project

What on earth could it be?

What on earth indeed Banquo??!
I'm beginning to think there is perhaps more here than complex feedback?
I've raise a new topic to see if any Gurus on A'Gon might have some ideas?
Have you any thoughts?
Cheers

I remembered that the TT-101 motor runs hot and needs to vent.

Hey Gary,
I hope you didn't cover the bottom vents of the steel 'cage'....as that is where the cooling air is dragged through to pass over the motor and vent through the side?
A hot Victor is an unhappy Victor :^(

Henry,
I left open the side vents and around 40 - 50% of the bottom vents. I have monitored the heat on the TT and it is normal.

It never gets that hot in my room (central a/c) so there is enough cooling to handle it.

As for your feedback blow-out - I look forward to reading the responses before I venture a wild-ass-guess.

Gary

Halcro:

Your issue is way beyond my ken to diagnose, but if it were me I'd be on the look out for audio gremlins.

Seriously though I hope you find what you're looking for.

Hi Banquo,
Thanks for your concerns.
You're right about there being space to fit Chris' long spikes under the Victor.
I feel like an idiot for not seeing that before?!
It is now possible for me to design a circular aluminium frame cut and welded out of 10mm thick flats into which I can just 'drop' the Victor.
After I get my preamp back with a working phonostage.......that may be my next project.
Plenty of scope for rigidity, levelling and isolation in that concept I think?
