Garrard GT35P-1 - what's this?

Post by saxtoda » 27 Oct 2014 09:47

Hi,

Someone recently gave me a Garrard GT35P-1 in average condition.

After some tinkering, it generally works with a couple of exceptions - i'm hoping someone can help me...
  1. there was a rattle inside the case - when i removed the back i found this metal piece in the bottom - i've no idea what it is or where it goes.http://i.imgur.com/lm4NEyY.jpg
  2. there is a 'thing' in the far left corner http://i.imgur.com/JFbf4Fs.jpg - not sure what it's for.
  3. there is speed variation on playback with a slight wobble on the plate - i'm assuming that some oil might help (i think it's been sat in a loft for some years).
  4. the 'reject' works to the point where it returns the arm, but doesn't drop it down or switch off unless the turntable is rotated a few times manually.
hoping someone can point in the right direction here.

Many thanks

Don't know what the bit you found inside is, but the "thing" in the top left corner is the base for a dust bug, which was a kind of extra tonearm but instead of a cartridge it had a brush and sometimes a velvet pad thingy that cleaned the record as it played.

The belt is probably shot and slipping when the auto mechanism is in operation.

Speed variation is almost undoubtedly caused by off-value electrolytic capacitors on the speed governor board and will only get worse as the capacitors, which are already about 40 years old, dry out. Replacements are cheap and in general better and longer-lasting than the Plessey capacitors that were originally put in there; and if you are handy with a soldering iron it's easy and worth doing. Do 'em all except the big power supply filter, which seldom goes bad.

Service manual is available right here at VE; the GT35P-1 was a cosmetically changed GT35P; the Garrard GT35 manual includes a supplement for the GT35P.

It looks like the core of a solenoid with a link that is supposed to connect to something; but I don't recall anything of the kind inside a Garrard GT35P.

Does the bit you found inside fit in the 'thing' in the top left corner? If so, it's probably just the support for the record cleaning arm that was once there.

Yea, it does...the first place i tried putting it, but as i found it inside the case i thought i'd check to see if it was important somewhere.

Thanks for the reply

Not sure if this will get read or not as it's so old and I'm sure you have got it all sorted by now but, could the piece in the first picture be a home made hook for fitting the drive belt?
