Title: 6 position tone switch - confusing layout
Post by: Purpleharmonix on November 09, 2012, 06:51:05 PM
Hi All,
First time post. I recently finished my dizzy with West Labs iron and nos glass. I'm absolutely loving it. I realized though that my tone switch seemed a little wonky. Laid out like Matchless it should start thin in position 1 and progressively get thicker moving clockwise to position 6. Mine does this but goes back thin at position 5 and 6. Being the left brained kinda guy I am, I wired my switch in alphabetical order as pictured on the current dizzy layout - http://www.ceriatone.com/images/layoutPic/matchlessLayout/Dizzy30Ceriatone.jpg - with position 1 being wired to "I" on the board. If you want it to work as intended ignore the alphabetical order and wire as follows. Switch position: 1=M, 2=N, 3=I, 4=J, 5=K, 6=L. The earlier layout doesn't use letters and just shows wiring. Hope this helps a future builder.  8)

I too just completed my build and I used the actual "Muchle$$" schematic to make certain the tone switch was wired properly. I wired the switch as L, K, J, I, N, M.

If you look at the cap values, this moves you sequentially from high capacitance to low capacitance. The layout diagram shows this sequence properly on the front panel 6-way selector switch...but if you're only looking at the circuit board, you can get confused by the apparent logical sequence of the letters.
