Re: Bush TR82B
Thanks Paul for clarifying that. It probabably explains why in the short term at least little trouble is seen with it as the white spirit disappears fairly quickly and in the long run, it is possible the mineral oil could cause some difficulty, but that certainly would be a very long term experiment to verify. Though for the most part, mineral oils are fairly non reactive.
The devil with plastic parts like post 1950's vintage radio & TV knobs etc is the plastic always seems to harden and crack with time. Bakelite knobs and even wooden knobs are much longer lasting. I was interested to see some replica Hacker knobs for sale on eBay recently. So for any radio restoration it's worth looking to see if they have been replicated.
