Looks like a touch of the Quad 33's going on there!

It think that styling was not the strong side of the British manufacturers of hifi gear compared to for example the japanese, danish, norwegian etc.

I think the silver Goodmans looks as smart as the Japanese contenders of the era but the small vol/bal/tone knobs give it an extra 'technical' look. Just enough difference to stand out, and then when you notice the fine graduations on the tuning scales, it makes the Japanese ones look a bit 'low resolution' in comparison. Full marks for styling!

The Quad 33's looks, I like a lot. When it came out it looked revolutionary. The Quad was bold and still managed to pull off 'cute' and made the competition look ordinary.

I wouldn't say that, and I am a big fan of Japanese and Norwegian receivers. The Goodmans one ten, 150, Leak 2000, Armstrong etc are all nice designs in their own way albeit not so glitzy and 'expensive' looking as Japanese ones. British designs tended to fly their own flag (they were all different) whereas Japanese designs all tried to look the same as each other but better - if you get my drift.

Yes, I appreciate the unique looks and that's one reason why I got the One-Ten to start with.
Just wish they had gone for another material than that cheapy plastic for the knobs an buttons when the rest is so solid.

Or is this old lubrication somewhere jamming moving parts?

I'm afraid the Hopf tuning capacitors used in these and other radios of the period all seem to seize eventually when the grease hardens, takes less than half a century ;)
There was a discussion in the thread Stuck tuning knob

Thanks for that info and link about the tuning capacitor.
Will be good help when I go for round two with that thing.

Had a bit of progress tonight: after bulb replace the stereo light works, yey!
But no life in the signal strength meter. If I measure voltage between the red and blue wires were they connect on the circuit board I get a tiny 0.17v when I have good FM and 0v when there's no signal. So there's a small voltage to the meter. But it's not moving at all. To little voltage or broken meter?
Im also still struggling with the tuning cap. I can get it working for an hour or so after lubrication of the shaft but the it slowly jams up after a while.
Maybe I have to try getting it out and apart for cleanup. But afraid I will mess it up. The cord, alignment and all that...

If we assume a meter resistance of about 1KΩ, 0.17V -> 170ľA. These signal meters were around 150 - 250ľA. The movement must be stuck

Re: Trying to revive a Goodmans One Ten receiver
 
Can this type of meter be opened for to try a repair?

Re: Trying to revive a Goodmans One Ten receiver
 
Just replace the whole movement, keep the housing and scale. I've done it with a couple of generic oriental 200uA meters in the past, but be sure to have a couple of donors whose innards match the faulty unit before starting.

Hi David!
Thanks for that piece of advice. Any suggestions about suitable donors?
I only found a few meters on the shopping sites that are vertically applied. Most are the ordinary horizontal ones.
But would this Russian model work?

Work? probably... but you'll find it different in sizes and shapes.

I've come across stalls at amateur radio rallies that might have a tray of new unused Japanese meters, often VU meters, but also all sorts of other scales. I've taken movements out of some of these and used them to rebuild faulty meters in a piece of gear I've been fixing. The internal movements are often similar even though the plastic housings and scales are different.

That meter looks very similar to this picture. I found this in my Armstrong spares (I think it is the 626 tuning meter). If yours is the same then it is very easy to swap the scales (they just slide out as you can see).
If you post some dimensions and it is the same as the one in my pic then you are very welcome to it. It's a 100uA movement but that should be easy to solve if yours is 150 - 200 uA!

You can get that meter from Element14 (Farnell). Part Number is 143509

https://uk.farnell.com/multicomp/mc3...509?ost=143509
Download the datasheet and check the measurements against your meter, I think you'll find they are a bolt-in replacement. One thing though, you may have to open out the hole where the small lightbulb fits into that meter but this is a simple job to do.

Thanks for your continuous help and advice!
Tonight I had the meter apart and could not but just confirm it being broken. The magnet is loose, jamming the meter movement seems to be impossible to get it right with required precision.

Arthur: I'm really interested in your offer. Will post measurements tomorrow. But you think it's possible to use a 100uA meter when it seems as if this goes to 200 uA?

I had exactly the same issue with one of these receivers. I tried all sorts of penetrating sprays and nothing worked for very long. I finally tried Caig Mechanic-ALL and it was like magic. It freed up the shaft almost instantly and it is still turning freely after a year. Problem is that it may not be readily available in most places.
