Thanks for this 

Hi Chas,
Fix it, don't bin it! Don't sell your skills short. One step at a time and like the Home Depot slogan, You can do it! We can help.

The speaker is easily repairable with tissue paper and rubber cement. The rattle in the tube may not be bad. All these tubes are available on eBay (Maybe except for the PenDD61.

Replace the filter caps and power up, preferably on a dim bulb tester. (Let us know if you need help on how to build one.) If it plays, then decide if you want to leave it as is or restore or "resto-mod" (half restore, half modify). If it plays as is, the easiest thing to do is to replace the "caps" (capacitors) one at a time. If it was my set, I would replace the 78 with a 6F7, get 2 solid state diodes, replace the rectifier with an 80, and whatever output tube you can get, be it a PenDD61 or a 42, the set will look original but perform like a 5 Tube job.

Good Luck and keep us posted!

OK, the idea is sound except for the fact that this set has been modified with components which I cannot read, so really need a circuit for. I could make a guess but I really don't like doing that. I have a variac and a dim bulb tester so no worries there. The speaker coil is jammed in the magnet as well as the cone torn, so a major rebuild is needed there. 

So, given that this is a major refurb I don't have the time to spend on this, so happy to pass it on to someone who does.

Yes, it goes against my ethos of " Fix it, don't bin it!" but that's why I came here, hoping for the help you've all provided, that help has made me decide it's too much for me this time.
