Is that necessary? It has a 3 prong cord and it appears to be grounded to the chassis.

The cap from the polarity switch to ground, while not "dangerous" with a grounded chassis (unless the power source is not grounded) but may trip ground fault interrupters if the slightest bit leaky.

It's no longer good practice to use them as they are being used in these amps, and when used for EMC control, they are a special type of approved part.

Here is something different

My Behringer BX4500H Bass Amp expired mid gig with a total wipeout of the power amp. Uneconomic to repair.

The BX4500H pre-amp section is really good with plenty of features so decided to salvage it and use as a pre-amp for rack mounted power amps. Similar pre-amp to the BX3000T.

Removed the heavy toroidal transformer and replaced with a small LV power supply for the pre-amp and fan.

Not a bad idea.
If you like the pre-amp you can salvage it. Tone is from the pre-amp.

Going further one can rip out the power amp part and replace it with a amplifier module. Some have power supplies that can power the existing pre-amp.

Making a fairly economical Hot Rod!

I had one of those in the beginning of this century. Nice clean tone, horrible OD/distortion, though.

In one of his videos on YouTube, Brian Wampler was talking about adding a Graphic EQ pedal in the effects loop to fix the tone of the overdrive. He also commented that he "fixed" his amp so it sounds good without the pedal. I suppose I should try to find out what he did... I have a Blues DeVille that needs some help.
