Interesting set, I never realised that Goblin made radios, I went to the factory in Leatherhead once, many years ago, to pick up an industrial suction unit - all gone and built over now.
The GZ32 would have been a plug replacement by someone who didn`t have a 5Z4, it`s higher rated and takes a little more heater current.

HT seems OK and all valves are lighting up. There is a crackle from the speaker when I touch the PU input so the GZ and the 6V6 seem OK, poss the 6Q7 is OK too. Radio's aren't my speciality so I'm bugging out on this one.
Interesting that a British radio of that vintage was designed using mostly American type octal tubes. Given the vintage I'd assume that the large stocks of war surplus were an economic choice.
It's a very cool radio, shame really that you don't want to restore it, OTOH perhaps it will go to its forever home. 😉

Some british valve manufacturers, such as Brimar, generally used used American designations, for some obscure reason, no doubt. Some of the types in this set had Mullard / European direct equivalents and others were manufactured by Mullard under American type numbers.
I doubt that by 1947 manufacturers were still relying on war surplus though some may have been.
It was not uncommon over here until about 1950 (excluding AA5 type sets) - I've even had post war sets equipped with Loctal tubes which would have been exceedingly uncommon in any other time frame.
Output transformers mounted on the speaker was a very common ploy here in the USA.. Another interesting oddity in this particular British radio.

I restored one of these radios, several years ago, and it worked very well. The radio was very sensitive and gave good performance after the usual suspect caps had been replaced. The only problem I had with is was the clock which had become a bit temperamental but managed to fix it. It's a big old beast, not really suitable for a bedside table!
