Finally plugged this in today in series with a light bulb. Supplied the missing 5Y3GT, and the radio worked straight off the bat. However the speaker sounds like it needs replacing.

By the look of it, I suspect that it may not be the speaker and perhaps it needs a birthday to rid it of the distortion. Some of that rubber wire is pretty sus & IF one needs its cover removed to rewire it.

Forgot to list the valves: ECH35 (without red shield), EBF35, 6SQ7GT, 6V6GT, 5Y3GT.

That;s not an ECH 35 in there. EBF35 is narrow like the other one and would have a wire band just above the base like the EBF35. looks more like 6K8G.

It says ECH35 on the base. According to a site I visited, it should be a 6J8GA. Maybe someone glued a different base on.

Yep, that model used a 6J8GA for the local oscillator. Model 5A27 oscillators used a 6SA7G valve (no TC). I suspect the former valve may have been less reliable than the latter, or perhaps less available?? I say this because both receivers were made during the same time ---circa '48-'49.

Did a bit more work on it. Replaced all the waxed caps. I found a 6J8GA and it worked - for half an hour - then silence. Touching the valve got it going again. It didn't take long to find out which pin in the valve base was dry-jointed. Soldered up a few pins and it sprang into life. In the old days we'd just replace it but we cannot afford that luxury now. Replaced the 6V6 grid bias resistor (was 700k instead of 500k), and the 6SQ7 anode resistor (was 1152k instead of 250k), and the 6V6 cathode electrolytic. The speaker transformer had been replaced in the past, so I rerouted the anode wire away from the 6V6 G1. The choke was open circuit and this had been replaced with a 150 ohm, 20 watt resistor in the past. Left it, as it was working well enough. Sorted out the stiff tone control and tuning pulleys. Only thing left is the speaker replacement... if I have one. Apart from that it works quite well.
