That skirt round the valve could be for a spring clip that goes over the top of the valve, or maybe for a screening can. It's very close to the speaker and the (mains?) transformer so magnetic screening may be helpful.
got side tracked to night picked up a couple of tools paid a good bit but good tools so was having a quick play with them then round to mates then back to cleanup just sat down half hour ago
i could dowith a space that i can do jobs and leave in the middle instead of clean up evey time i finsh but cant see that happening
Because electroytics are polarised they are unsuitable for AC unless specifically designed for it, so they tend to be marked AC or DC to avoid confusion.
I use Cricklewood Electronics as 1st choice for components, the cap in the last photo looks like 0.02 uF
Same uF greater voltage is fine.
BTW mF really means milli- farad (never used), it's more common to use uF to represent micro-farad.
Since that was made the preferred range for capacitors has been revised so just go for the nearest value. Electrolytics have a fairly wide tolerance and tend not to be used in critical parts of the circuit.
What was the result of my suggestions in posts number 32 and 40, regarding re-seating the valves, identifying the valve type numbers, checking that all the filaments ( heaters ) are on, and checking the filament continuity? After that has all been done, I would suggest we could move on to check that HT is present, then worry about capacitors.
ashamed to say been doing lots this week i did try to remove the valves one was very free but snaped the rubber band and the one that lights is stuck solid
there rest ive not tryed as are the bands needed ? (if there there i assume there needed)
its on the to do list but worried about the one that does not seam to just pull out
I've never seen valves held in by rubber bands. Yes, metal screening cans with an internal spring at the top, or two expansion springs like this:
but never a rubber band.... it may be a local DIY bodge. Anyway, as long as you are not planning to use the radio as a 1955 pre-Walkman, going jogging with it powered by batteries, the valves should stay in place well enough for static mains-powered use.
