Hello, I am new to this site and have a question about replacing one of the electrolytics in this radio. The schematic shows part number 45 as a 25uf - voltage not listed. The radio has what appears to be the original Mallory can with
a value of 30uf @ 500 (peak) volts. A little internet research has shown that a 450 volt can be used to replace this? I've never gone backwards on voltage and am unsure how to proceed so I thought I'd better ask before wasting parts.
Do I need to use a 500 volt cap here or can I use a 450 volt (that I have plenty of) to replace without something going bang?
Second part of question. The tuning capacitor is very loose - it has three "slots" with rubber grommets that have dry rotted so now the entire assembly is loose. What are these even called and are replacements available ?
Thanks for your help!
