I ended up using the Sams Photofact version. It is the same exact chassis as the JC Penney 6248, and there are two issues where this chassis appears in the Sams Photofact CB manuals. Issue 254 and issue 274. I'd scan the pages if I had a scanner, but the scanner on my machine broke, and I...

If anyone wanted to build amplifiers and sell them with a very low likelihood of getting caught, they could do it on the dark web. The problem is, you have to figure out a way to get people to know you can find them on the dark web, and how to get onto the dark web. The FBI has a hell of a...

Keep looking on Ebay. There are several signal generators that are quite good that can be had for low $. The last one I bought was a Fluke 6060A/AN that was broken. After he accepted my $70 offer, and shipping, I ended up paying about $120. The guy had quite a few up for sale, but it appears...

I have ordered tons of stuff from Adafruit in the past, and I have only ever had one other problem, and that was due to a faulty part. I don't blame them for this. I think Adafruit is a bit expensive, but they do have some very helpful things that nobody else makes. I did send a message to...

I don't know where the damage happened. It seemed packed in Adafruit's box just fine. I think it's more a problem with Quick cutting corners myself. If they had simply used some cheap locking washers, I believe both problems could have been avoided. The first, because the transformer would...

Well, if it was bad design, Marantz, Sansui, Kenwood, and many others had bad design. They seem to age badly, even with little use, so I think it is something to do with how they were manufactured. Anyway, I don't know if they are all made by the same manufacturer or not, and I'm not sure what...

I didn't check the transistor to see who manufactured it. I didn't even look to make sure it was a 458. I just went by the schematic and assumed it was. I must have been right, because it worked. I didn't throw it away, so when I get back to the shop Monday, I'll check to see if I can...

I would like to complain, but I don't care to try and return this one. I have two now for the price of one, they both work fine, and I would feel like I was taking advantage. They don't make it easy to just complain to Adafruit. I would have to send a message for some other reason, such as...

Another update. Here is a video of the replacement they sent. LMAO I am apparently the luckiest guy in the world.

Found the bad transistor, and it was a 2SC460 that was bad. Replaced it with a KSC1845, and all is well with the frequency stability. Now to do an alignment, and call this one done. I'm going to bet that the squelch problem on the other radio is one of these transistors as well. If this were...

I've see seen what these do when they fail, and they often fail strangely. For instance, I recently had a problem with a Marantz amplifier, where it presented multiple different symptoms. It would start out playing fine, then it would start clipping more and more, until I was only getting the...

Oh, the other thread. They will have to wait until tomorrow.

458's?

Most of these are 2sc458 transistors. It's not a big deal, as I have tons of KSC1845 transistors to replace them. These others I'm not sure about though, and although I'm not finding any 2sc458s handling anything that gives a frequency, I am finding others that look like them, and what I was...

When restoring audio amplifiers, the rule of thumb is that whenever you come across transistors that look like outhouses, replace them with new ones. Is this something that is followed with CB radios as well?

Well, I finally found the squelch circuit, and those numbers are way off. That Q254 was Q108, for example. I've opened up this other radio in the mean time, and when I first turned it on, it was receiving very quiet, and then slowly dropped down to nothing. That suggests to me I have a bad...

I finally decided to look at this pair of 6248's I got from the guy in Cincinnati, and the first one I have on the bench seems in good shape. I have only found two problems. First is the RX light doesn't work. Might be a burned out LED. The bigger problem is that it won't squelch. I have...

I don't ask for them. I just see them. On top of that, people have heard that I will buy old radios and they bring them to me. I'll give a couple dollars for just about any old CB. If they are worth more, I'll pay more, but for just your average, run of the mill AM only CB, $2 - $5 is all I...

I don't know how much 10 codes were ever used, but since the early 90s, when I started playing around on the CB, there are only a couple ever used. 10-4, 10-20 is kind of used in terms of "What's your 20", and 10-7, although that last one is used very little. As for trucker slang, there is...
