I had an old valve tech give me this trick for bringing an old device back into service.
Remove all valves except the rectifier (if it has one). Put a ~40W bulb in series with the mains cord to form a non-ohmic current limiter. Switch on.
If the electros are duff the bulb will light brightly, then over a couple of hours as they "reform" it'll gradually dim until it's effectively out. There may be a detectable glow from the heater current of the rectifier valve (if it has one). At that point you can power down, wait for the HV capacitors to discharge (or discharge them gently) and put the valves back in.
That generally prevents them from exploding in a (usually) spectacular fashion.

G'day John,
Thank you for your post. I went on a bit of a hunt online. I found this link Australian radio series (1930s–1970s) - National Film and Sound Archive accessed 18th of September 2023 from
https://www.nfsa.gov.au/sites/defaul...on_amended.pdf
It amounts to 244 pages of goodness. No I could not find Mandrake in this Australian publication. However, I did find it here though accessed from Mandrake the Magician | Old Time Radio. Plus here ... Mandrake The Magician 401111 001 First Episode, Old Time Radio - YouTube
Perhaps it was not Mandrake on the radio that I did hear back then. I will have a closer look at the contents of the 244 pages later on to see if I can narrow it down a bit. Perhaps it was a Raymond Chandler or similar detective? It was a fair while ago that I sat down and listened to it.
Some time later .....
There are 15 results for the word 'detective' within the Australian National Film and Sound Archive publication. With a brief check one of these results is no less than 'Philip Marlowe'.
Kind regards
Lionel
All good Lionel
I run an analogue face on my Apple Watch,
I have analogue clocks on my walls and digital Amazon screens throughout the house.
I prefer paper workshop manuals to online ones where practicable.
I like high tech vehicles and enjoy simple machinery as well.
I do all my own mechanical, electrical and electronic repairs.
I don’t own vinyl, cds, dvds or video cassettes anymore,
I don’t have a tv antenna on my home,
I don’t play online games,
I stream everything, Audio and Visual
I use a laptop for shopping, work and CAD only,
And my Mountain bike has a computer and motor assist….
I prefer live music to all other options
I’m struck between both…
Take care, hope you can find a suitable replacement for your receiver.
There's any number of specifically retro-styled radios:
Explore Our Range | Roberts Radio
Roberts Rambler Range | Retro Radios | Roberts Radio
CP-100 AM / FM / Bluetooth / AUX│SANGEAN Electronics
Radios with dials:
Shop All – Tivoli Audio AU
In my experience these electronic dials work better than one radio I had as a kid where the knob was connected to the actual tuner by an elastic band ...
Modern multi-wave radios:
ATS-909X2 FM/SW/MW/LW/Air Receiver│SANGEAN Electronics
https://www.aussiestormshop.com.au/p...craft-channels
There's still a wide range of this kind of radio sold in Japan.

Re the Station Selector, I recall that in my experience the Tuner was attached to the knob via an Elastic BAND "type" of belt & that in turn rotated the Tuner. You may have already checked this but worth looking at.
All those years on it would be a miracle if said belt if fitted it wouldn't be be in one piece or even capable of gripping it's "pullies"
Good luck with getting it mobile again Lionel, it doesn't deserve the misc junk skip yet.
Hope this helps.
Also relevant to this thread, I was at an auction on Sunday. One of the lots sold, which I did not bid on, included amongst a lot of other stuff, a cardboard box containing the remains of a home made crystal set, built on a wooden baseboard with a front panel cut from a plywood butterbox - as shown by the printing on it. It was similar to the one me and my brother built in the 1940s.

Hello John,
Very relevant John. I think it was a rite of passage for males to experiment with crystal radio sets in their youth. This included my first decade of life being the 1960s. I helped my older brother - okay looking back with the benefit of hindsight - I probably hinder my brother with his interest in crystal radios. My elder brother was born in the late 1950s. Years later at a time when I still had not found my vocational niche, I was working as a Trades Assistant and the local electronics electrical appliance repair shop. My shop manager was a radio nut. He mentioned that at the time - the mid-1980s, there were international competitions where different radio enthusiasts competed in building crystal radio sets. The winners produced sets that had the greatest range of reception and the best sound quality. All this had to be done within the guidelines of using components traditionally associated with building crystal radio set. No, I did not become one of these crystal radio enthusiasts.
Kind regards

Hi Lionel et. al.
When I think of my first crystal set I made 60+ years ago a diode with the number BC108 comes to mind. Am I correct?
Listening to the radio on Sunday nights in Hobart, the two detective shows I remember were "Spiral Ten" and "Hunt The Man Down", the latter having very scary theme music. Anyone else remember them?

Hello Peter,
I cannot recall much of the components in the crystal radio set that I was hindering my elder bother with. I went online and found this link ... Accessed 20th September 2023 from, How to make a batteryless (crystal set) radio - BuildCircuit.COM. It includes a parts list and circuit diagram. From memory the international crystal radio competitions required the competitor to build as much of the components by hand from things like a roll of copper wire. A core that they made themselves so they could wrap the wire around it. So not a case of buying a set of off the shelf components.
Kind regards
Lionel
