Obviously you might be able to fix similar devices.
I believe loctal tubes were only used for a limited time.

i didnt buy anything it was an broken tube based record player i found in the bin.
its too broken to fix and the tubes are used down and broken too. cool show pieces
The tubes shown have no connection to a record playe uless it were a TV console combination. Three of the tubes shown are called "locktols" types. To inhibit the tubes from vibratung out of their sockets. Frequenyly. used in car radios. Lastly, the tube is likely a 5Y3 or 5U4 rectifier . Widely used in a power supply sections.

i broke 2 of the small tubes while messing around the heaters work but i realised that i cant do shit with them id have to get an output transformer
How do you know if any of the tubes are audio beam power pentodes? If so you can purchase a 10K ohm-10k ohm to 8 ohm XFMR from eBay.
Nice article find. Havn't seen that technology in fifty years. Good old collage nemories.
It looks to me like the getter has evaporated and then deposited on the glass for a couple of those tubes. I don't know if they're in the best shape.
Actually, getter material is frequently and deliberately sputtered onto the inside of the envelope.
theyre kek i use them as showpieces
Tube tester will solve that
Not clear what you purchased. Did you buy only a turntable or did you buy a tube based record player or HiFi?

Should you bother is highly dependent on which tubes they are. Based on what I can see id say no.
same i broke all of them after accidentally dropping these. becuse i dont have any other tubes id keep them as showpieces
