5e3 coupling caps to reduce bass, question.

In that amp it'll be one of the V1 tube's 0.1uF (100nF) orange caps with '104' written on it. These are the larger orange caps that come off the plates of V1 (socket pins 1 and 6 respectively) and go to the (respective channel) vol pot inputs. Take a look at a 5E3 schematic and layout, and you will see these 0.1uF caps labelled.

IMHO, these sound a lot less muddy if replaced with 22nf (0.022uF), but by all means try 47nF and see.

As you are obviously a noob, take care to ensure the filter caps are drained (and the amp is unplugged from the wall) before putting your fingers inside.

 

you could try

a .047 in place of the .1 and a .022 in place of the .047

 

I put a 0.022uF on one of my 5E3 channels as well. For single coils stock caps helped fatten up the tone, for P-90s or humbuckers it got woofy and muddy.

As far as a switch, you might have to solder a 1M or larger resistor at the switch (or the caps) to ground to reduce loud popping when flipping the switch - it'll need a reference to ground at a spot like a plate coupling cap.

 

Looking at the eyelet board: (L to R) .047, .047, .022, .022, .022. It sounds great with sc's

 

This is a updated 5E3 I built. It sounded awsome but it was built for someone else so I had to let it go. This arrangment complely isolates the channels from each other where the tone control only effects channel one and channel two tonal/response options are controled by the Tweed + switch on the back.
