Hi Tony,

No, I don't want to buy a restored radio as I enjoy fixing things; lots of encouragement on here, so have regained my motivation.

I have been watching this thread for a while, now it's time for a little input.
£20 for a few basic components is rather hefty, I usually pay in the region of a fiver for 10 caps, the same price for 10 bulbs too.
Electrolytic cans are put on the reformer at an early stage during any restoration to determine whether one needs to be ordered/re-stuffed or not, most don't need immediate replacement but may be checked 5 years down the line, unless loud hum happens first.
Ebay is the best place to find cheap parts, even valves at 99p are found to be in very good condition with the plus side of getting a dead set going again.
Whatever the OP does, don't go spending well over the odds when cheaper alternatives will suffice, unless the set happens to have a value approaching a grand!

All the best with the restorations, Rick.

Have a look at the radio's you have and decide which one you'd like to tackle first. Loads of help on here and no doubt some will be willing to donate parts if there are any problems with obtaining suitable types (unlikely). Here's to your first successful restoration!

The Bush PB12 does have quite a few wax capacitors in it around 20 ISTR.


However most are in positions where a bit of leakage will do little harm, there are 3 in the tone correction circuit alone but as these are across the output transformer they can do little harm so don't need immediate replacement.
The only replace on site is the usual grid coupling capacitor C17,
Most of the rest are decoupling or AVC.


Change C17 fault find the rest?


If you need to change them all for longevity/reliability reasons then in general it will be cheaper to buy radial caps designed for use on PCB's than axial capacitors you just need to extend the leads they never look as good as a nice axial replacement but that's the trade-off


Although you can buy exceptionally cheap caps from China these days

As an example


Cheers
