I'm hoping to just clean the relay without disassembing the amp, but
the
contacts are a little hard to get at.
Start with something non-abrasive like a piece of cardstock. First run
it
through dry, then take another clean piece of the same with a drop of IPA
or contact cleaner on it.
If that doesn't do the job, use a aontact burnishing tool. Jonard is
probably the most common. If you need something small, the disposable
type
are the way to go as you can cut them into smaller/shorter pieces then
grab
it with a pair of needle-nose pliers, forceps, or whatever. After the
burnishing tool, run a piece of cardstock with IPA or contact cleaner
through just to make sure nothing is left behind.
