Oh bummer, what amps do you have? Big power supply caps are usually super easy to swap. I have some Manley monos that are just a few philips head bolts, it’s a few minutes to swap including taking the bottom covers off.LOL. My other hobby is high end (yes, not a term exclusive to reefing) audio ..... my tube amplifier recently blew a $20 capacitor .... by the time I had paid to ship the 80 pound monstrosity (it’s just a mono amp, too) to and from the manufacturer in CA I was out close to a grand. Sadly, electronics are a big mystery to me.
