Series/Parallel speaker switch.
« on: June 04, 2022, 11:21:56 pm »
I built a series/parallel speaker switch using a heavy duty DPDT for my bench, and it proved to be much more useful than I anticipated. Thought I'd share it.
If anyone wants a diagram, let me know, I'll draw one up

Something like this?
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!

I made one a few years back but found that after some time using it the internal parts of the switch starting rattling ..  making a really strange sound.. it was mounted in the cabinet.
