I agree with David , wrt to the 940 and and the EA12 , although I wish I could have got my examples for the prices he mentioned.
My EA12 cost me just under £400 but was a very good example in good condition, however after about 6 months of regular use I had to rework it completely with new caps and quite a few resistors.There are some Vinknor inductors in various places like the slot filter and the bandpass filter , if these were to go it would be a problem finding replacements.
A nice performer and useable.
I have just sold my 940 , this was an ex "Reuters" unit and was very lively it too has a product detector again cost me just under £250 with the silky smooth dial even general coverage are useable on ham bands.
These old comms valve sets like most boatanchors are deliberately designed to be "tank like" that is how they get a lot of their stability, the chassis are very rigid , in the case of eddystones many had the main RF sections encased in a die cast aluminium chassis. Once warmed up it is amazing how thermally stable they remain.
If you want performance , general coverage as well as very useable on the Ham Bands go for Racal RA117E ( if you have to an RA17) or a Collins R390A. Certainly if you are going to spend over £200 a RA117E/ RA17 is achievable and over here in the UK there is enough information to keep it going. I had a RA117E in the early 90's and wish I had never got rid of it.
