FDP Forum / Fender Amps: 1985 - Current / Fender Deluxe 90 reverb 1999 model made in Mexico HELP

This amp has been very good to me for the time I have had it, it's clean channel was the most pure aspect of this amp, far superior to my cyber deluxe clean channel,so it was my go-to amp when I would plug an effects board into it.

Yesterday it suffered an unfortunate accident in which the power supply receptacle was damaged by the cord being smashed down. Two inside clips broke, the instant this happened, the amp began to hum loudly, and continues to hum at different dbs depending on how the power supply was angled in. I don't know why this would be.

keep in mind, before the receptacle was broken, the amp did not hum, but after, the humming is now intense, even on a non-distortin channel.

How is the inside supposed to look? My amp has wires that are completely tangled, and I don't know what causes the humming to intensify. Is a wire touching where it shouldn't? Please help. I will include pictures of the inside.

Welcome to the FDP.

Be *very* careful poking around inside your amp. There's enough voltage to KILL you in there.

Sounds like a ground may have come loose, but photos would be a big help.

Think seriously about taking it to a qualified tech.

Yea, go straight to a tech with what you're describing.

If there's something amiss, plugging it in more won't make it fix itself and could do damage.
