Default Options for replacing turntable in Grundig radiogram

Hi,
I've acquired my dad's pride and joy Grundig Mandello radiogram, which has a Grundig Automatic 36 turntable (aka Philips GC036) in it which has died :-( The irony is is that I was probably the one that broke it playing around with it as a kid!

Just wondering what replacement options there are for the turntable, even with a better one? Am I too optimistic that anything from around that era that
1. physically fits
2. can be powered (hopefully inbuilt)
3. I can wire to the audio input
will be a possibility?!

Thanks!
DD.

You might be able to fit a BSR or Garrard changer (I have a bit of a soft spot for the 2025TC), probably not without some woodwork.

Please note that the power for these decks are 110V not 240V.

Most Garrards with 4-pole motor can be wired for 110V. I think there would be enough
space to fit a small step up transformer if the incoming mains supply was not usable.

Ideal candidates for the replacement would be a Garrard AT6 or AT60 or Model 3000 or 3500. If you do not need an autochanger, then a Garrard SP25 or a BSR MP60 or P128. They are all roughly contemporaneous.

Please bear with me if I'm being a bit slow here!

The radiogram has a 220/130/240/110 voltage selector on the back, and is (unsurprisingly for the UK) set to 240V.
Does your comment mean the turntable is always at 110V, regardless of the main selector on the back?

Thank you!

Those decks are 110V and are powered from the 110V
tap on the mains transformer. There is nothing to stop you working a 240V deck directly to the mains switch.

What is wrong with the Philips turntable? The reason I ask is that unless you have a replacement turntable at hand, a non working S/H one might well cost 30 upwards plus maybe a new cartridge.

Transplanting another make will also require the plinth re-working to accommodate the position of springs etc which support the turntable. All possible but it will need thinking through.

There is on this site a description of repairing the Philips turntable which will give you an insight to the skills you need.

Good luck

Chris

I agree with trying to revive the Philips deck. I have done a couple of this era and they aren't too bad. What's wrong with it?

In response to what's wrong with it... well...
My father "had a quick look", and something fell out . From the schematic on radiomuseum.org - looks like metal clip 78 or 99. Possibly related is the haphazard behaviour of the start/stop buttons too. And the up/down lever doesn't work - but that looks like the easiest to sort.

The motor was stuck, but I've persuaded it to turn smoothly now...

To be honest, that schematic scares the living daylights out of me. I've never tackled anything this mechanical before

Anyone got any advice for someone tackling one of these for the first time - apart from being very methodical?
Dismantle the lot, labelling everything + taking photos as I go?
Would I have to identify all the problems from underneath ?!?!?

I'd love to have a go, but can see it ending in a big mess of random bits :-(

Dont dismantle everything at once, take lots of pictures, the main problem is dried out grease.

If you are really stuck, you can send the deck to me, I can repair it for you.
