Nice looking amp and cab! Where did you get the metal for the faceplate?

Tube Amp Building - Tweaks - Repairs / 6V6 JCM800 channel switch

« Last post by JGk on March 07, 2026, 09:20:39 am »

Hi doing a JCM800 6V6 on an old chassis I have that has a single input and I would like to use a switch to go between the high and low outputs instead of re-drilling the chassis. I was wondering if anyone had build one and had a schematic or a layout available.

Do you have the schematic in a more visual format?

6L6 is an American valve, it was not very common in the UK/Europe. The Mullard/Philips valve series were the dominant market share in the UK.

The El34 is a 25 watt tube with a current draw of 1.5 amps

The 6L6 is a 30 watt tube with a current draw of .9 amps


I'd think you could go with the same PT to run cooler with the 6L6 and get more power


Why do you think they used the EL34 over the 6L6?

Photo for reference.

I made both cabs.  Stained pine with ply baffles.  Made the faceplate on the laser machine at work.
(don't mind the small badly repaired grill cloth hole on the head cab... I made it out of an offcut)
