60A225 power/tone switch

Emil All Messages By This Member #32312 开云体育 I need a Hallicrafters part number 60A225 power/tone switch. That is the same part number for the power/tone switch in the S-40, S-40A, S-40B, S-85, SX-99 and probably several other Hallicrafters sets using the essentially the same tube lineup. It is the SPST switch element that has failed.? The? front rotary wafer element is still working. Emil, WD4SCZ
Jim Whartenby All Messages By This Member #32313 Emil Does the switch still "click" when turned to the OFF position?? If so, take a close look at the switch solder lugs on the switch wafer.? There should be a rivet on each solder lug that connects to the internal switch contacts.? Ohm the rivet to rivet connection to see if the problem is actually corrosion of the rivets causing them to be insulated from the solder lugs.? Soldering was earlier suggested for tube sockets that have ground rings that are also riveted to the chassis.? Clean and solder the rivets to the tabs as necessary. If this was not the problem, try spraying some penetrating oil into the switch body and exercised the switch several times.? This also works to eliminate a scratchy volume or tone control resistive elements. Regards, Jim Logic: Method used to arrive at the wrong conclusion, with confidence.?

Emil All Messages By This Member #32314 开云体育 The switch action is erratic. Contact cleaner has had no effect.? I could jump the contacts and plug the radio in to a power strip, but if there's an organ donor radio out there with a good switch, I'd like to find it. 73, Emil? de WD4SCZ On 5/17/2025 11:44 AM, Jim Whartenby via groups.io wrote: toggle quoted message Show quoted text Emil Does the switch still "click" when turned to the OFF position??

Jim Whartenby All Messages By This Member #32315 Emil You didn't mention checking to see if the ON / OFF switch rivets are high impedance thus causing the switch to be permanently open.? You could connect an ohmmeter to the line cord? plug and use a pick to probe the switch solder lug / rivet mechanical connection to see if you can read a low resistance on the ohmmeter.? A little solder goes a long way to make a good contact between the rivet and the solder lug.? Been there, done that. Jim Logic: Method used to arrive at the wrong conclusion, with confidence.?

Emil All Messages By This Member #32316 开云体育 I'll try a little solder on the rivets and lugs. From the plug to the first lug is OK. Nothing on the other side, switch is open at the rivet.

don Root All Messages By This Member #32318 开云体育 Guys , my memory is failing, but? the contacts of most pots/switches that I recall don’t have visible rivets .. do they ?? But maybe some older ones do ?? has anybody got a picture?
