They also experimented with modular designs. Choice of RF and AF modules on that one.
My wreck is T19D, says so on the plate. At least the sockets are still on it. Only volume control, audio transformer, mains transformer, cabinet, back, scale and mains lead missing.
I can colour laser print onto polyester film and put that behind glass.
I have a mains transformer from a Philips that was missing scale, all the sockets and audio transformer.
I have audio transformers.
I might have the octal valves, or a nearby friend may have them.
Now what sort of box?
Yours sounds easy compared with mine providing the IF transformers are not coreless.
Instead of glass, acrylic sheet? easier to cut and drill.
You have the advantage of no nasty plastic trim to cause you mental turmoil.
Output transformer is a bit trick with its feedback winding for the complex tone control.
Easy, go for it!
