Discarded chassis recognition... - UK Vintage Radio Repair and Restoration Discussion Forum

Paul_RK · 27th Mar 2022, 1:15 pm

Seen on a steep bank half a mile from home, to the side of a path that runs beneath a road: does anyone happen to know what it's from? "Motor supply" is printed by one (or two?) of the several sockets, so presumably a stereo record player / radiogram / music centre. Could be some parts of use to someone, it's fairly free of rust so can't have been there long, but I'm not sure whether I could readily retrieve it.

Philips by the look of the components and construction style?

Refugee · 27th Mar 2022, 6:11 pm

It has got old style battery plugs and sockets on it.

Nickthedentist · 27th Mar 2022, 7:40 pm

Yes, used by Hacker, Pye and others for mains, HT, pick-up and audio connections internally in the 50s and 60s.

Paul_RK · 27th Mar 2022, 8:04 pm

I was curious as to what a different view might reveal, so approached the spot via the track below, but the scramble up the bank to reach it would have been just a little too treacherous. Maybe tomorrow I'll go that way with a walking stick and see if I've reach enough from the pavement above to give it a good shove down the bank for easy examination... then either remove a few potentially useful bits or help clean up the town by parking the whole lump in our attic.

I thought that it had a bit of a Dynatron look about it so did a quick Google search and came up with this thread on the Dynatron HFC52

https://theartofsound.net/forum/show...52-with-L78-TT

which shows a very similar set of internals to the ones in your photos.

Paul_RK · 27th Mar 2022, 11:09 pm

Very similar indeed: thanks and congratulations James, it must at least be a close relative. And, via Ekco, Dynatron were by then a part of Philips, though the Dynatron name was later dealt to Roberts. I thought I saw a pair of separate small sub-chassis each with a power transistor, as pictured there, when I first spotted the remains, but couldn't make them out yesterday when taking the photos.

I think it's part of the SA29 chassis. There's a module on one of the PCBs which deals with the stereo sound, that's failed on mine, it'd be great if that could be pulled for my player. I'm not 100% sure where it is or what it looks like as I was told about it, rather than finding out for myself. I believe it's black, in mine anyway, it could well be different colours on different units.

Thanks

Those four-way plugs and sockets are always useful.

Paul_RK · 28th Mar 2022, 10:59 am

Ah well: surveying the scene with a view to possibly retrieving the remains, I'd need a twelve foot pole to give them a solid push down the slope to an accessible position. I might be confident enough to scramble up to them from below, but it's getting down again that would present too high a risk of a trip to A&E. Apologies then to '77, it looks as though the whole thing is doomed to decay in-situ for probably the next twenty years or more. Now that I know what it is the pair of output chassis and the toroidal mains transformer are easy enough to spot. If a couple of our enterprising teenage members happened to live nearby I'm sure they would contrive a way to get the thing... oh, except we hardly have any teenage members...

Could you poke it down with a line prop, fishing rod or long garden cane? Two garden canes gaffer taped together? Obviously, don't put yourself at any risk.

Paul_RK · 28th Mar 2022, 11:27 am

Hmm... I can't think of anything I could readily take there. We had a nice pair of extending metal clothes line props in the NE, but didn't bring them with us to a first floor flat where hanging laundry out is forbidden, and I doubt they would have been long enough anyway (though, yes, taped together, that would suffice). Full (simple) directions available by PM of course to anyone local who fancies the challenge.

Kentode · 28th Mar 2022, 1:11 pm

Break out the grappling hook!

jamesperrett · 28th Mar 2022, 2:30 pm

More importantly - is there a Lenco turntable lurking in the bushes somewhere?

Or did someone buy it for the turntable and strip out everything else?

Do you know, I'm actually quite tempted to give that a go. It could take a few minutes' "fishing", but would surely bring the items, or most of them, down in the end, even if a plug or two were pulled out first. We don't have a grappling hook, but I'm sure if we did it would come in useful for... something else...

"How hard could it possibly be?" Used by Jeremy Clarkson frequently, usually immediately before an accident!

Just make sure you know how to get to A&E...

I have just realized it is the chassis and not the beer can we are trying to identify.. J.

Michael Maurice · 30th Mar 2022, 11:31 pm

If you can fish those modules out, I'd be interested in them as I'm going to design a modern version which hopefully will be a bit more reliable. Some of the transistors are obsolete as are the connectors.

paulsherwin · 31st Mar 2022, 10:18 am

You can make a 'grappling hook' from a couple of wire coathangers. Very useful things, wire coathangers.

TowerRadio · 31st Mar 2022, 12:17 pm

Maybe a powerful canal-fishing magnet? Les.
