That's a later model, as it has fixed bias for the audio tube. The yellow cap, blue thumb wheel, electrolytic cap and a few resistors on the audio board are the giveaway. The D201A doesn't use the "B" side of those two tubes to control the meter like the 23 channel radios did. It uses a UA741TC...

I'm a little late to the party, but I had the same problem with one of those I worked on. The crystal was off-frequency when I measured it and had to replace it. Was all good after that.

Being a 40 channel radio, they were from 1977 and later.

Sounds like the LSB crystal is out of tolerance and the trimmer can't bring it onto the correct frequency. I've seen that quite a few times in those 858 PLL radios. They are 45 or 46 years old now.

The leg is missing because it's not needed. The leg and the metal tab of the transistor are connected, so there is no need for the leg. This is used as the regulator for the 14 vdc circuits. If you measure about 14.2 vdc on the output of that part which is the emitter, it is okay. The emitter is...

Here is a diagram from the circuit board D201manual. The board is the same as the vox radio's board, except the vox board used round sockets and pins and the later D201 and D201A used square ones. The diagram clearly shows the orientation of the caps.

Do you have a manual or schematic for it? If not, you can download them here: https://web.archive.org/web/20210302170832/http://cbtricks.com/radios/tram/d201a/index.htm. There are board diagrams in the manual that will help you identify the parts. Looks as though most of the resistors that...

I've done that many times over the years for people. They just have to realize they won't have channel 39. Only 36,37,38,and 40 unless they want to somehow add the extra 4 MHz crystal that the 40 channel radio has.

Here's a NY Times article from 4/28/1983, the day the FCC ended CB licensing. https://www.nytimes.com/1983/04/28/us/fading-cb-craze-signals-end-to-licensing.html

In the 60s, Wolfman Jack from the "X" just over the border from Del Rio.

This may help you. Many I have worked on just need new gears.

I have that problem here in NYS. NY bans all kinds of stuff from being shipped in, so I just use a friend's address over the border in PA and have it shipped there.

Here ya go.

Are you sure it's the display segments and not the resistors.

Right. Everyone around here back in the fifties and sixties also had the white dishes with the outer colored edge. I think blue was the most popular, but they also had green, yellow, and red. Everyone also had the Peyrex cookware. There was a Corning kitchenware store in downtown Corning.

Ah, I understand. Corning, NY is only a few miles from here. Corning Glass headquarters are here, as well as their research department and a cellular-ceramic substrate plant. Many people in this area have worked for Corning over the years. It's the biggest industry in this area, but used to...

Steuben glass was made in Corning, NY.

Lou Franklin called his compressor that he sold a DSP (Dynamic Speech Compressor) which always got confused with Digital Signal Processors.

And the majority of hams today used to be and still are CBers.

Tramdr didn't post that, I did. Here's the manual that I also posted with those others about a year ago.
