It got me once a few years ago. What I thought was going to be the parallel Playstation to SDCard iso device, turned out to be something else. As you noticed, its based of what is highlighted in the pictures available to choose from.

Hmmm. after looking at the picture again... Maybe the RF Gain/NB knob may be better??

I imagine you just have to move wires around to do just that. I looked up a picture and figured its best to use the "tone" knob. I dont like a low tone, so always liked it higher. Solder/wire those wires internally simulating either all the way down, or all the way up... Then with the mic's...

May Big Bear rest easy. I knew it was here in the forum I first heard of the live stream you could watch. Damn....

I can't recall how I did the 138 XLR as I did it a few years ago. I think I ended up hunting down a 8v source and ran the wire to it. Your way is definitely a ton better. :)

Maybe not today, but if it comes outta nowhere someday, then it might be. :) Aside the aging old capacitors, I had a 138 XLR that at first I thought it was TR5, but then soon learned the actual audio chip was dead in the water. :D Once that got repaired, it was making an aweful screeching...

Was there a small transistor that was prone to failure on the receive? I have to dig out what part it was. I think there was a service bulletin for it for the 138 XLR radios, but think that one of yours uses the same board. Symptoms include bad reception or no RX at all. TR5 is the one on the...

I would convert it to a 4 pin, then put some push buttons on front for the up/down fuction. :) But that is too much trouble.. :P I tried selling one last year here locally for a whopping $5 and nobody bought the damn thing. :D

It was nice having some wires that fit just right lol. Good stuff. :)

The 23 channel SSB base/mobile radio and the Slant Face SSB/mobile radio had that 6 pin like Smokinone mentioned. Out of all the SSB Sears radios I have, the AC cord was more common. I think I only ever had ONE DC 6 pin connector. I ended up wiring directly to the board inside on some of them.

did you adjust SSB Mic Gain? Give it some more if it can.

I have been meaning to recap the slant face AM only Sears Roadtalker and put in a board to lower the deadkey. I do like the receive audio and transmit of that radio.

I was late to chime in, but yep.. Outta an old Sears Roadtalker SSB radio. ;) (The first Sears SSB radio, not the slant face.) There is a resistor in there to clip out (much much easier than to desolder the whole board just to remove a leg of the resistor. I did do a guide here on doing the...

LOL!! I never realized it till you mentioned it just now. I learned something new. Thanks for the laugh Nomad.

It was worth a shot. I got an older President Washington 858 chassis radio which took away several hours trying to troubleshoot. I purposely put it up high on a shelf in the garage where I need a ladder to get to it. :D Keeps it out of reach so I do something else instead of trying to find out...
