Wkg on a radio that needs a few 5mm inside diam, say by 20mm long. These are the neoprene rubber type which need to be soft and flexible as its part of a drive mechanism.  I say this as old pre used ones may not be suitable.

I can buy a bag of 100 but will never use anymore and I have too many items like this.

3 or 4 would be enough and of course I'm happy to pay postage.

thanks Gary]]>

Health issues slow me down a little but my doctor tells me that I am in good condition, (for my age!)


Anyway, back onto topic. I recently came across a basket case of a radio, and because it was a model I've never seen before, I put my brain into neutral and bought it.


The radio is from about 1963, and is a five valve, live-chassis type, compact mantle. It has a four position rotary switch giving

• pick -up
  
• broadcast band
  
• SW-1
  
• SW-2.
  

A paper schematic label was glued to the inside of the cabinet, so I figured that would be enough to fix it.


Apart from one missing knob and and a cabinet that would make a cabinet maker cry, I began to fix the radio knowing that I would give it away after fixing it.


I disassembled the set as much as I could, cleaned off the chassis and had a good look at what was under all the dust. First the mains fuse did not look right. Hmm. 25A fuse? Seemed a little high. I replaced it with something around a quarter amp. Next I replaced all the paper caps. I changed the electro in the output valve's cathode, and re-formed the main filter electro at a low mains input for a few hours.


The power supply is a little odd, (read dangerous) in this set. The Aerial, the aerial's earth end, the pick-up, and the radio chassis, are all isolated from the mains by some wonderful sixty year old paper capacitors. what could possibly do wrong? Apart from the obvious, if the active side of the mains is the side being the, radio's earth, (a bus-bar from tag to tag underneath the chassis), the tuning gang and the dial drum will be live. It is connected to the-bus bar.
In this case of my radio, the insulating grommets had turned into a white goo and flowed away decades ago. Now every piece of the chassis would become live. Hmm. thinking of that 25A fuse again.


Long story short, it's now working.
Because the schematic was so poor, I used it in conjunction with the circuits for National EE-345J and GU-362.


If I can, I will try to attach a photo of what I am working on now.Let' see who can recognise it.

I recently got a Blaupunkt Köln series Y to use on a Lamborghini 400GT that didn't have an amplifier and I'm wondering if anyone who's more knowledgeable them me would be able to inform me if the amplifier of the Blaupunkt Köln series S is the same model or compatible with the series Y?

Thank you in advance.]]>

Bought for scrap in an auction, its a bit of a horror, as in Frankenstein's personal wireless?
No makers name, no clues either.

Cabinet looks home made. Chassis looks to be in part a production item but massively altered and modified.
Huge odd speaker, permanent magnet, with output transformer mounted on the basket, held in the cabinet with no less than 11 woodscrews of sizes various! 

Is there anyone out there with enough interest to respond? 
If there is a bit of interest shown I will do a photo shoot and article on the efforts made to get it to produce some sound.

I believe the company is from Australia, closing shop around 1980. 
This model was clearly made for the South African market.
Interesting that they called it a "Transistogram" when it is a valve unit.
The valve line-up is DK96, DAF96 & DF96.
Should anyone have any additional info and a schematic I would be very grateful.
Thank you.

I've just received an immaculate Roberts R300 complete with original paperwork & receipts etc. from 1965. It's missing the central tuning knob - cream with a brass inset...

Anyone got a spare? Pretty please?

Also, has anyone restored one of these? What to look for, apart from the usual caps etc. The AFnnn transistors I know can get tin whiskers, so how to deal with those (if they are there)?

Thanks]]>

1. Anyone got a catch for the back of the case? (see photo) - I suspect the same catch was used on lots of Roberts radios
   
2. Anyone got a strap? Long-shot, that!
   
3. Anyone got a "scrapper" case that I can salvage from?
   

Thanks

Nick

Seen for sale, Ekco A22, no bids yet and ends Tuesday. Perhaps the £180 starting price or the add on cost @ 32.94% is putting bidders off.
