Remove metal plate that covers knobs
 

I need help how to remove metal plate that covers knobs (tuning and volume), under which is screw to remove knob, they are glued, and I do not want to bend it or damage it, a photo of the radio. Thank you very much for any input.

Re: Remove metal plate that covers knobs
 

How do you know that the plates are glued on? The knobs are more likely to be be push-fit than held on by screws. Have you tried (very gently) pulling the knobs off? You may need to try (very, very gently) levering them off if they are really tight.

I have two radios of this type, one with these plates and another that have removed them .... Yes, retaining screws are underneath....

Re: Remove metal plate that covers knobs
 

Hmmm ..... the front/face of the knobs seems to be bigger than any hole[s] in the plate i.e. holes that their screwed shafts apparently go through. Therefore, irrespective of the fact that the plate may be glued-on - the knobs must be removed first i.e. prior to removal of the plate.

Ergo - you must access the rear of the plate in order to access and release the screws retaining the knobs. This will probably involve removal of the interior lining of the case etc. (The latter is likely to be glued-in too .... so great care will be required - possibly involving soaking with a benign solvent, or even steam.)

P.S. It looks as though a similar process will be required [i.e. removal of the case lining] in order to remove the speaker and clock too ....

If they are glued in place then maybe heating with a hair dryer will soften the glue enough for them to be gently prised out.

Is it possible the OP means removal of the knob "brights" in order to gain access to axial screws that secure the knob to the control shaft?
A picture of the dismantled one would help.

That's what I am assuming: I guess the tuning capacitor is a 'polyvaricon' type - these often have a hole down the end of the (very short) tuning-spindle to retain the knob.

To remove - you've got to remove the metal disc - as suggested, warming with a hot-air-gub/hairdryer may soften whatever glue is used to hold the metal plate to the centre of the knob.

The shafts usually have two flats and a screw hole down their ends.

I had to do a similar thing to a small far eastern transistor radio from late 60s early 70s, and I ended up using a heat gun with a little ipa to soften (what I think is contact adhesive) and a soldering aid hook to get underneath the aluminium disc. I used tin foil to protect other parts of the radio from the heat gun. Care will have to be taken that the ipa doesn't take the print off the disc and you don't distort the aluminium disc with the hook..

Mr. Dickie, a picture of the dismantled.

Any idea how the aluminum sheet comes off.....Thank

Re: Remove metal plate that covers knobs
 

Is the aluminium plate glued on to the leatherette material or does it have small hooks at the back that can be lifted up, for example with a small flat screwdriver ?

Re: Remove metal plate that covers knobs
 

The only thing I can think of that would be thin enough to get into the gap between the knob and the aluminium disc would be a scalpel blade, give it a bit of heat from a hot air gun then very gently try lifting it with the blade, it’s going to be very difficult to remove it without damage, and also not to stab your fingers with the blade!

It appears to me that the re-assembly will be a bit of a tricky job, too. The aluminium plate, once removed, will need to be re-aligned to the index arrow for correct tuning, won't it?

Re: Remove metal plate that covers knobs
 

Mr. ColinTheAmpMan1, look at the small hole, where you read X1OOKC, to align.

Re: Remove metal plate that covers knobs
 

I was hoping there might be something like that. Good.

Re: Remove metal plate that covers knobs
 

Put some lighter fluid on the disk.Its good for softening the glue
If you can lift the disk slightly to let the fluid in would be good
If that fails then
If you can protect the disk with some foil Useing a hot soldering iron on the disk can help
Cheers Pete

Hi Henry, well if it was my problem, and the knob has got to come off, I would drill a small hole down the centre of the knob squirt some WD 40 down towards the centre of the screw and just undo the Philips screw. If you start using solvents or heat prying tools you have a chance of destroying the total knob structure. If and when the knob has to be reinstalled you could "glue" a bead of aluminium over the drilled hole and a man on a galloping horse would never notice it, Ha Ha .In fact it will then be a unique radio regards Brian.

Re: Remove metal plate that covers knobs
 

Years ago if they had to removed it would have been ripped off and new metal plate bought. Today its much more difficult and time consuming.
Could you put it in a plastic bag, placed in the freezer, hopefully making the glue brittle. After 24 hours work knob between finger and thumb. The knob brights are often missing due to the glue deteriorating with age. Personally I would not risk using heat, Its so easy to do damage to the set.
