« Last post by kinkydoints on September 11, 2018, 07:11:15 AM »well I have not tried this kind of repair before but after some fabrication and tuning , the switch works again on /off volume. it might not be a permanent repair , but it's until I can find a replacement.
Was wondering on this s120 there is a standby /receive switch , used to keep the units tubes powered up and hot for instant on...if i used a potentiometer of the correct resistance . without a switch. I would like to use that standby switch to power on / off shouldn't be to hard to rework the wiring .

Other Electronics and repair / On / Off volume switch repair? poor old hallicrafter
« Last post by kinkydoints on September 09, 2018, 01:32:43 PM »in my first stage of this attempt to repair a hallicrafters s120 , I found that this on/off volume switch was used to power up straight from line cord. no fuse . I decided to remove and clean contacts and wiper on the inside with some contact cleaner . upon doing this the on /off switch stopped working and let the shaft rotate too far around. then would not return to off ... no click off . opened the switch up to find that the finger inside that goes into the switch was worn bad enough to miss the slot or slip by the slot . I seen a technique to fix plastic with super glue and baking soda . ? was wondering if this just way too much work ,and be better off trying to find a replacement . any idea where to find a replacement with the shaft as long with internal switch . shaft looks to be 3" to 3.25" long this is listed in the part list as a 2 meg ohm 30% 1/8 watt variable, volume control switch with internal switch. ya guess im stuck trying to fix that finger . got some small files to fine tune the repair, might take longer than i hoped to get this radio up and running.

« Last post by kinkydoints on September 08, 2018, 06:07:17 PM »thanks Buddy I have done a little looking at the insides of this unit as well as some reviews of other videos on youtube and found that diode...is connected to the upper bumble cap and also the first fuse resistor in my picture it is just visible under that rectangle fuse resistor upper right corner has the yellow wire to it from the line cord/volume pot, is blue with a aluminum body look but does test as a diode . and has diode markings ---|>|--- just got my cap kit , from hayseed some one has done some work in here that is not really up to standard...that brown lac line running from the AC input right to the volume control. and going to the standby/ receive switch . more home work yet to do . Im hopeful this will work again. as of now just static . as for that 455 khz BFO circuit module , on the .jpg schematic the JL Fuhring addition looks like the upgrade for a later date.

The back object with silver ends looks like a precision resistor or capacitor. An ohm meter may tell.
In the second picture that flat pack with the 6 legs is a resistor pack. There are multiple resistors inside. think of it as a crude attempt at a IC.
