Thanks for the info Steve.
Yes that record deck is going to be horrid. The cartridge is the same as fitted to several players I've seen over the years, although it's not the one you twist with two parallel styli. I think the deck may possibly be either be belt drive or if not, it might be idler drive with a belt for the auto return. I've had one similar.
I found this at the back.... I think it used to be a belt....
Anyway, I'd better stick to tv related matters under this section.
