Re: Trying to revive a Goodmans One Ten receiver
 

Hi!
I think Goodmans recievers are pretty rare over here. Never saw one before I bought this one. Thanks for sharing those nice pictures by the way.

Well tonight I replaced the reservoir capacitors with Nichicons of same capacitance. Not my finest hour with the soldering iron (still waiting for that one... :) ) but both the One Ten and yours truly survived the operation.

But man, new caps are really small compared to the seventies stuff. Had to makeshift a bushings solution for the new ones to fit the clamps.


Now onto the bulbs. Guess the service manual will have the specs for them listed.

Re: Trying to revive a Goodmans One Ten receiver
 

Hmm, finding the right bulbs here in sweden was a bit harder than expected. My normal go-to webshop could not identify modern equivalent lamps for the scale and indicators when I sent them the parts number from the SM.

Do any of you guys happen to know what lamps to get and from where (that ships internationally if abroad)?

Re: Trying to revive a Goodmans One Ten receiver
 

There is RS Components, 104-878 look ok for the 12v ones and 104-597 for the 14v ones? packs of 10 though and do check if they are suitable as I only had a quick look.
Steve.

Re: Trying to revive a Goodmans One Ten receiver
 

Thanks Steve!
Yup, those seems to work. will order promptly.

Re: Trying to revive a Goodmans One Ten receiver
 

On this matter: is there any way to access and change the stereo light and tuning gauge light from the inside or does the front have to come off?

Re: Trying to revive a Goodmans One Ten receiver
 

While waiting for some lamps to show up, I did a bit of cleanup and oiled the cabinet. Turned out quite ok.
And of course I couldn't stop myself from hooking it up to my main system when I had indoors in the warmth (getting a bit chilly in the outhouse where the workshop is).
It really liked being hooked up to its fellow Brit, the Garrard Zero 100 :).

That looks lovely!

Re: Trying to revive a Goodmans One Ten receiver
 

They are a good looker, aren't they? That slide-rule tuning scale !

David

Re: Trying to revive a Goodmans One Ten receiver
 

Yup, it's a classy looking piece of kit for sure!
But speaking about the tuning scale, this has an issue I hope you can assist me to sort out.
The tuning will only move to the right and not easily. Not at all to the left. Knob turns but not the scale indicator. Seems as if the variable capacitor gets stuck.
I thought this was caused by working in a chilled out outhouse and carefully applying heat with a hairdryer on the variable capacitor made it work.
Thought it would sort itself out coming into a warm house but problem persists.
The capacitors mount is a bit crooked, don't know if this is the cause and can be fixed.
Or is this old lubrication somewhere jamming moving parts?

Re: Trying to revive a Goodmans One Ten receiver
 

The capacitor looks skewed on its mountings. That might indicate something wrong.

The slide bearings for the pointer in some sets can wear and grab a bit in one direction only.

FM tuning is done by that pot on the end of the variable capacitor. It tunes varactor diodes.

David

Re: Trying to revive a Goodmans One Ten receiver
 

Got the tuning unjammed! This by first cleaning the capacitor bearings with no residue contact cleaner and a lot of exercising. The some contact cleaner with lubrication and more back and forward tuning.
Very careful not to get any spray on the capacitor fins.
Also cleaned the tuning string with isopropanol.
Managed to get the cap to sit more straight by adjusting the three mounting screws. Seems as if the rubber grommets on them where unevenly compressed.

Once the tuner moved I got good reception and sweet sound quality. Alignment seems good getting local stations where they should be on the scale.

But even though I get flawless FM reception the signal strength meter is not moving.
Can this be related to the stereo lamp being broken?

Re: Trying to revive a Goodmans One Ten receiver
 

Well that was a short and sweet success. This morning the tuning was jammed up again 8-o. Hmm. So, do I need some other kind of lubrication for the shaft/bearing of the variable cap? If so, I´m grateful for suggestions. WD40-type? Sewing machine oil?
Or could it be the fins of the cap gripping?
Also thinking the cord needs to get more friction. Is the suggestion I found googling about using bees wax for this good? :shrug:

Re: Trying to revive a Goodmans One Ten receiver
 

This has been an interesting read!

Regarding the tuning, could it be the rubber grommets on the tuning capacitor have aged, and the varcap gets misaligned too easily?

Re: Trying to revive a Goodmans One Ten receiver
 

Yes the varcap was not sitting straight in the mount towards the chassis (as I posted a pic of a couple of posts ago)
But yesterday by adjusting the three mounting screws I got it sitting pretty straight. But you are right about the grommets being aged/compressed.
But afaik the pulley on the varcap is now straight and inline with the cord.
So I think the problem is either the two bearings were the pulley and varcaps is held in the varcap housing not running easy enough, or the cap fins having friction against eachother somehow.
But seems as if when I ad cleaner and lubrication to the bearing points this helps. Just that the effect doesn´t last.

...and this maybe in combination with the cord slipping.

Will investigate further.

Re: Trying to revive a Goodmans One Ten receiver
 

Carefully lube anything that rotates in the tuning 'chain' using thin silicon lube accurately applied from the end of a pointed tool like an awl. I do this all the while when restoring my vintage receivers. Silicon oil is very sympathetic to most materials and can be applied safely and with confidence. It's a friction build up problem at many points and they can all be eased.

Re: Trying to revive a Goodmans One Ten receiver
 

Thanks for that suggestion! Think I have some of that stuff around somewhere. Will give it a try (if I can find that "somewhere"... ;D)

Re: Trying to revive a Goodmans One Ten receiver
 

Take care not to get silicone lubricants onto sliding contacts such switches, sliders of pots and the grounding wipers in variable capacitors.

David

Re: Trying to revive a Goodmans One Ten receiver
 

Yup, that silicone stuff you don´t want to get in the wrong place :o

Re: Trying to revive a Goodmans One Ten receiver
 

Waiting for the 14volt lamps before tearing the thing apart next time for another go at the tuner when I replace the bulbs.

In the meantime I found a review of the One-Ten in the december issue of 1972 Gramophone Magazine.

Interesting read that reviewer John Gilbert ended with the statement:

"The Goodman Model One-Ten is a real challenge to the various tuner amplifiers imported to the UK and it is already making inroads to European markets; a fine example of British design and craftmanship."

So apparently it helt up well against the japs, yanks and other recievers in the early seventies.

Re: Trying to revive a Goodmans One Ten receiver
 

Has anyone ever seen the multicoloured version pictured? It must have looked very striking.

Here's one: https://cdn.globalauctionplatform.co...d/original.jpg

The controls look like Lego!
