Following on from my tape deck question from before I thought I might as well ask about some other old junk I've accumulated. Well I say "I", it's actually my missus that is in the habit of buying any old audio gear she can get her hands on in a vain attempt to recreate her Dansette days on the cheap (have you seen the prices of those bloody things now?), I don't discourage it as it helps keep her knackered old 7"s off my nice turntable but it has led to a collection of old turntables and radiograms in various states of disfunction.
One of which is a Garrard GT20. Pretty simple machine and mostly works fine, the sound is decent enough for what it is apart from the fact that it plays ever so slightly slowly, not enough to pitch everything down into comedy Barry White territory, that at least would be funny, but just enough to be annoying.
I changed the belt for a new one but it made no difference, so I figured I open the base up and see if there was a pot or something I could adjust to speed it up slightly (of course if it was the GT25 I could have adjusted it with the pitch control but no such luck on the GT20). To my surprise there was nothing under there, just a motor with the mains lead going straight to the terminals, that's it.
How does that work then? Did they just spec a motor that would spin at the right speed for the given input voltage and pulley gearing? And if so is that why it's running slow because when it was made the UK ran at 240v and now it's more like 230? If that's the case, what the hell do I do about it? Some kind of voltage regulator? I'm really not interested in spending a fortune on this, as you can imagine.
