All the old Eddystone, Racal and other similar items are much sort out by aficionados as are the 'bottles' that are part of them. Some years ago I sold, at rallies, those sort of things to make space for newer items. Regarding cost of nerwe products, well, I have an old adage' there's no pockets in shrouds'! :D

alan i had one out of a Hercules bomber for years. then i bought a yaesu
 
When I came of the RAF in 1957 I had about 300 (mainly B7G) bottles that I'd taken home at weekends and added loads of EF50s & similar items out of the government surplus stuff I had bought. When I moved south in 1961 I had to get rid of them and gave most of them away to friends - in those days you could still buy them for a bob each or 1 / 3d and the semiconductor age was already with us. Now they're around three quid each and made in Russia - that's if you've got much use for them!

B7G was that a mini valve holder?..... i have SEEN EF50 at rallys for a lot more than.£31577981587287.png
 
B7G was used for things like 6C4 triodes, EF91 & EF92 pentodes and the battery portables like 1T4, Pete. EF50s used a B9G base. I know I should have hung onto them, but you can only transport so much gear about. When I lived in Bournemouth my middle son (an avionics engeer at that time) had crammed my garage with all sorts of aircraft bits - I could not get in there. When my youngest son bought the house, his first job was to take it all down to the tip becauise his elder brother had nowhere to store it! The middle son now has loads of recording studio equpiment stored in a commercial store on which he is paying £150 a month. Crazy!

i have a battery lift up lid radio in my loft. always wanted a akai recorder.
 
The red EF50 reminds me of the 'Viewmaster' TV made by my dad. He modified it so that it could be used as a radio during the day, (TV didn't start up until the early evening). He was quite pleased with that modification because when you switched to the TV position it was almost 'instant start' as most of the valves were already warmed up. (I think we have gone backwards with digital tuners, they must be slower to 'warm up' than the old valve sets!)
 
I remember seeing them in Ireland, Police and some army units had them, pretty useless, as I remember, no good in the Divis Flats, or any high rise, or mountain area's. Paul Ref#249
 
Hi Pete,

That Wessie brings back some memories, although I never had one.
But I did have a load of AM10 Cambridges, one I converted to 2 metres FM,
and another to a receiver for VHF airband - I think the rest were broken up for
spares or sold.

Incidentally, for anyone who likes Sailing By, if you have a short wave receiver,
the Netherlands Coastguard broadcasts the forecast for the North Sea twice a day
at 0940 and 2140 UTC in English followed by Dutch. Frequency is 3673kHz (80M band),
and mode is upper sideband.

Kind regards
Dave

true they were useless. Back to back unless they went through a repeater to boosed them. or a talk through unit.
most utilities. the gas,water electric.AA. RAC. the emergency services had them as well. They were reliable but very bulky.
 
From the Autumn 2020 Garden Thread. Do any old radio chaps have trouble with sunspots ?

HF Radio Propagation and Sunspots »
Sunspots and Propagation | Ham Radio School.com

Flares and CMEs can send enormous amounts of energy and charged particles hurtling into collision with the Earth's atmosphere, where they can cause magnetic storms that disrupt or alter radio and cell phone communication and can wreak havoc with electrical grids. ... ...............:grinning:nuff said or i will be a geek
 
Hi,

Anyone buying EF50s these days would probably only want them as spares for
a piece of equipment that used them, rather than building something new.
I think these days you would probably havea task trying to find the B9G bases too.

Incidentally, for those who have never had one apart, they are not a metal valve
like the black American Octals, they are glass valves with a metal screen.

Kind regards

I've sold a few valves with one of the electrical wholesalers I worked for early 70's that was. Ones I remember being PCL 805/85, EF, DY, Transistors BF etc
