No I haven't replaced the AF118 yet but it arrived today so I may as well try it.

Interesting comment Robin.

 

They're way before my time entering the Trade (1970) so I never saw one but I did hear about the Portarama from other engineers who remembered it, generally causing an intake of breathe and a look of despair suggesting that they were glad to see the back of them.....

Considering the technology of the time, I reckon it works very well. It's now 55 years old and probably working as well as it ever did.

Yes the intake of breath is about right. This set came out when many were cutting their teeth on small transistor radios and the transfer of valve knowledge to transistors caused some a few headaches. Going on to a full TV was a bit too much for some.

Its a fine picture, can't remember how well they worked in the field, only saw a few of them. They have not left any nightmares in my head so they must have worked reasonably well.

...and I did quickly try the new one. It didn't make a scrap of difference so I refitted the original. At least I have a good new spare if ever it's required.

It's all ready to reassemble. Apart from the missing telescopic aerial which I'm not really bothered about, it will be a good example of this early solid-state TV.

Pictures of the assembled set will follow.
