I've read a bunch of info indicating caps going bad if they sit to long so my question is I have a couple amps that have been siting and not powered up for quite a while 1-3 years just because of things out of my control. So what precautions should be followed or taken so not to cause anything to burn up or blow up. I'm mean really there's original amps from the 50's still operating on the original components. Are there any obvious signs indicating of any problems from sitting. My amps are in a 10x12 bedroom and I worry some theiving bastard will hear them and set me up for a burglary.
P.S I used to have access to a large shop to play these at theyre happy volume but the situation went away
Thanks
