Ah, "10-turn" as in clarifier control? This would suggest that you expanded the coverage of the clarifier way beyond the factory's range of a few kHz. I never encouraged this for that kind of radio since it has three PLL crystals, one for each mode. You have to expand each one separately. Never...
Here is the most information about the Siltronix 1011 and the Swan-branded versions you'll find on the web. Scroll down the page to the green crossbar. You'll see three zip files and four pdfs that should fill in a lot of blanks about this radio.

Nice job! Don't see a lot of foil-pad damage. We had one of those. Daily use will grind it down faster than a Hakko, but if you only use it on weekends, it should last a fair while if cared for. Kinda like power tools from Horrible Fright. At one-third the price of a Hakko, it can last...
If you'll have a look at the solder side of the front corner of the main pc board, under the channel selector, you should see a handful of one-eighth Watt resistors, usually 100 ohm. They will be stretched across the solder side of the board near the board's outer edge. Simply removing them...
Pull all the fuses. Put them back, one only at first. See if your receive-side current draw is there. If not, put in the next fuse and glance at the current meter. Should at least narrow down where to look. The other way is to unsolder the jumper wire feeding power to each two-transistor pc...
So, if the SWR indicated by the radio only rises when the amplifier is keyed and putting out power, this means that the amplifier's input circuit is not imitating an antenna with a low SWR. The amplifier's input circuit should fool the radio into thinking that it's keyed into a...
The walkout method is what I use. Much easier to suck the solder from a hole when there's no lead wire in it. Pretty sure I posted suggestions about handling the "orphan" pads that have no trace attached on the solder side. They tend to detach when you suck the solder from that hole. We use a...
I thought for sure I had snapped pics of a Clipperton some time in the last 23 years. Didn't find any. I know we lost a few folders of radio/linear pics in a hard drive crash 15 or so years back, but who knows?
Couldn't even find that kind of image on line.
Been too long to just describe it...
The ability to find a knob in the dark without taking eyes off the road will continue to be a selling point to drivers. Too bad the marketing departments haven't heard.

All 10 or 11 of them. It's an old-age/mileage problem. Once the first one or two go bad, the rest of them won't be far behind. Troubleshooting "just one" capacitor is a waste of time. Time better spent replacing them all.
And a cheery footnote. The electrolytic caps inside the clock/counter...
Ah, seems like a self-explanatory kind of modification. But only if you have already done it, I suppose.
Bypassing the band switch is a common "hot-rod" modification, especially among hot-rod types who like to disregard the, ah "red line" and burn the switch contacts that way.
I don't remember...
I'm so old I remember when 10 meters was dead as a post, and some folks were agitating to expand the overcrowded CB allocation up above 28 MHz. Argument was that the hams aren't using it. CB WAS overcrowded, even without skip traffic.
And then the sunspots came back. The "give some of it to CB"...
Used to have a couple of 6JS6 or 6JE6 tubes that had softened the glass on opposite sides where the anode got hottest. One of them was just sucked inwards, a crater on each side. The other one sagged enough to touch the anode and opened a small hole at the pit of the crater. The tech I employed...
Don't know if this story has reached this forum yet, got a link to this story from an old pirate-radio pal. Yeah, Steven's old. My advice is to steer clear of Belarus.

The RCI29 "10-meter" base radio is built into the same cabinet used for the Galaxy (RIP) DX2547 40-channel CB. Has the new circuit board used in the X9 and other models. This customer complained that the Tone knob didn't do anything. It's not strictly a "tone" control. Technically it's only a...
No, that trimpot only adjusts the sensitivity of the meter while transmitting. Doesn't affect the transmit signal. The internal construction of that model has changed multiple times in the last few decades. If yours is different from the one described in a web page, that's just business as...
