You shouldn't do any damage removing the valves, but my advice to you is if you don't need to remove them, then don't! Cheers, Jerry |
Thanks Jerry. I merely want to clean the contacts and socket. The radio is working pretty well after recapping, and looks cleaner than shown in the photo (taken before I started restoring it). The alignment still needs some fine-tuning. The thing is that slight wiggling of the UCH42 produces some crackling noise at the output, which in a way should be normal, but I want to rule out dirty/oxidised contacts, and I didn't yet remove any valve from the set. I also have a spare UCH42 just in case.
