Have just tried it, tacked in temporarily just to try. Stood the transformer on the chassis on the RHS near the speaker. Gives 120 v onload, so only 3 volts high, that should be OK. So I will probably fix it there.

IF transformer repair work separates the men from the madmen (with a delicate touch). Couldn't resist this remark: You might want to use NP0 ceramic capacitors in there, they are temperature stable and good for RF work. Again, enjoying the updates on this work, Tim, thank you.
@Timothycan6 күн бұрын
Yes, to be honest, Joe, this is not a great radio anyway, it's very basic.. I have gone with the caps I happened to have, and it now works OK. I've still got the line voltage transformer to sort out, though!

Elon Musk is fond of saying the best part is no part. I wonder what happened to the diode? 🤣Might replacement of the rectifier valve by a (selenium?) diode explain the high B+? It seems to me that this radio might benefit from Manuel Caldera's methodology, tracing out continuity, measuring component values where possible and colouring in a copy of the schematic as you go?
@Timothycan9 күн бұрын
It turns out there is a silicon diode in full view on the top-side of the chassis. (More on that, in my next video). The high B+ was (I think) due to the transformer putting out more than 117 V. I remember altering it (40 years ago) to get close to the correct voltage. I'm now thinking I should get this set to work at 117v as originally designed, before worrying about the adaption to UK voltage. The heater chain current needs to be 150 mA, so I need to check that first.

I'm with you. If the radio was a valuable collectable then originality might win out but as it is I'd go for the better sound option. And if you do sell the radio on you can always include the original speaker in the deal if the buyer requests it.
@TimothycanАй бұрын
Yes, good thinking. I think I will write on the speaker with a Sharpie to remind me which radio it came from.
@matambaleАй бұрын
Agree with you Tim, the Cossor deserves the better speaker. I can see why you'd use the original only if you can find a more powerful replacement magnet of exactly the same dimensions, in the interest of 'pure restoration'. Congrats on getting that speaker apart and re-aligning it though! Bit of work that must have been. Fine skill to have at hand, too.
@TimothycanАй бұрын
The speaker I fitted is an ELAC, and I did some research and found that it is a German company, (although the one I fitted was made in England). They have a good reputation, whereas the original speaker was unbranded.

Tim: Congrats on finding that issue. Funny but just yesterday a channel called "RestoreOldRadios" (recommended) posted a video on correcting a rubbing coil on an otherwise pristine speaker. Looks like a lot of very careful work to re-center the cone. Since you're unlikely to use that original speaker as it is - it might well be worth the time spent to investigate a repair?

I won't open the other one now! It looks like the two coils are separate units - i.e. not coupled together at all like an IF transformer. I now have a circuit diagram, so I might be able to see which coil it is if I look at the chassis again.

It does look good, but is actually a budget model, so there is only the one speaker, no tweeter. It sounds OK when I play music through it using Derek's modulator circuit. There is a connection for an extension speaker, too. Only mono though of course.

330 mm 3mm dia silver steel bar was the stuff, I remember. It's expensive, though, probably because of the silver content. One company you could try is simplybearings.co.uk but you need to get the longer lengths, as the 160mm ones are too short. Select the 325mm option instead of 160mm. Other companies do supply this too, but if you order three of the 325mm lengths you will get free delivery. If you're not in the UK just search for 330mm length 3mm diameter silver steel bar. Hope this helps.
