Re: 60A225 power/tone switch
¿ªÔÆÌåÓýEmil, there must be enough old S-40¡¯s and such around that? a donor part should be available somewhere.? So for now, jump the switch and use an external power switch.. like you mentioned. ? From: [email protected] [mailto:[email protected]] On Behalf Of Jim Whartenby via groups.io

I checked my stash of parts and I don't have a direct replacement.? I may have a pot + switch that has a switch assembly that would fit your tone control.? That would still mean that you would have to disassemble your defective switch to make the repair.? So if you run out of options, send, via DM, a photo of the rear of the tone control so that I can check to see if I have a similar switch in the stash. Regards, Jim ?

Don't have any other pictures handy, but not hollow rivets as is often seen. It is the head end of the rivets that hold the contacts.The rotary switch that tone control portion works fine, it is the SPST part that has failed. I could sub a switched pot or simply jump it as a solution. Drilling out the rivets and trying to fix the innards is not a step I want to undertake. ? Emil ?

It is a four position switch tone control with a SPST AC power switch attached.? The half meg tone pot with power switch goes back to the hallicrafters S-14 which might be the first hallicrafters with a tone control.? The S15 uses a 1meg pot for tone control with an attached power switch. ? The Mallory catalog illustrations at the bottom of page 4 shows rivets.? Illustration M26T actually points out copper rivets.? But Don, you make a valid point, component construction has been improved over the years.? Perhaps Emil can take another photo of the other end of the three "pots"??? ? The rivets I expect to see are rolled rivets.? These were used in the switch that I repaired in a Philco of approximately the same time period, IIRC. Jim ?
