Default Help for newbie with HMV that doesn't turn on

Dear All,

I inherited an HMV record / stereo system from the 1950s. I've attached photos.

My grandmother said that it worked when she used to turn on it sometimes in the early 2000s. However it went unused for a decade. I plugged it in and turned it on but absolutely nothing happened. Left it on for 20-30 minutes and nothing started or kicked in.

I don't really know where to go or how to get the electrical issue resolved. I like to think that it's something simple like a switch. I'm not bad with electrics and audio equipment generally, but I've never seen something like this internally (photos attached).

Any ideas on what I should do to try and diagnose the issue or what sort of electrician could look into this?

All help appreciated. One radiogram restorer in Australia said he would not just fix one thing but do a full restoration and I really don't want that. Aside from the fact that it was horrifically expensive, the record player condition generally seems good given its age.

I thought it might be the switch (photos included) but that's a guess.

The system is an HMV N3-4Z

Best Regards

Get rid of those croc clips on the speaker to start with. I assume they're someone's crude attempt at adding an external speaker? If they both contact the speaker's frame they'll short-circuit the output stage and could cause damage.

As for the no switch on, simple continuity testing with a meter on ohms range will show whether power is likely to reach the turntable and amplifier. I'd suspect the OFF/ON switch, but I'm not one for replacing components because I think they might be faulty. I like to prove it.

Do you have a model number or name?

Circuit here:-

Looks like there's a single pole mains switch and a socket which the deck plugs into.

The OP seems to have disappeared. I hope nothing bad has happened to him.
