i opened the radio and it is full of some TRACON gray capacitors. They only have their negative strip printed, voltage and capacitace markings - no series, no temperature marking, nothing else.
My question is, do you know of this brand of capacitors and how bad are... -

So I'll start things off :
My name is petabyte and I'm a forum junkie. :oops:
I've been off the wagon for a number of years and countless times I've tried to stop but it's useless.....
