Groundhog,
The biggest problem with those tone switches is the switches themselves. The way they are wired, if one switch fails, it takes a bunch of others with it. Sort of like cheap Christmas lights. And those switches do fail, often. I forget which side (bass or treble) has the real problem switch, but basically the cheap spring metal loses its spring and will no longer touch the contact. When this happens, the downstream series connected switches will no longer function. I have 3 Zenith chassis with this exact problem.
