Still not as good as "My Dying Bride", or "Septic Flesh". Best metal programs on the web were WFMU in Jersey. Pretty sure that's where I heard those two. 73

Every mount I can remember to fit that size hole was discontinued decades ago. Hustler had one with a small swivel ball to compensate for the tilted mounting surface. Used a1/4 inch by 20 pitch thread for their stingers and for that mount, rather than the 3/8-24 that's become the standard since...

And it works. We have installed at least one of this exact kit for a customer. Just hope you don't come down with Hanta virus from the mouse schmoo. 73

Mark 4A receiver band crystals two point oh. Layout is cleaner, but a bit if wasted board space. Just one little boo-boo. A closer look: Yeah, I got the wire colors reversed on the screen-print legend. Not to worry. Fixed it by swapping the order the frequencies area stored in the...

Ahh the 811A. To quote my old friend Toll Free, "All the linearity of a half-wave rectifier". 73

My take on this amplifier is that the relay that transfers the antenna from transmit to receive is just too small. Not enough current rating. The receiver-preamp relay next to it is the exact same part. Big enough for that job, but not to handle the full output power of this amplifier. Don't...

Um, receiving or transmitting? Or both? 73

Mileage is an issue. This type capacitor is commonly rated for some number of thousand hours of circuit stress. A barn find with 500 original miles is less likely to have bad caps than a heavily-used specimen the same age. Even if they are all good today, they will 'remember' how old they are a...

That's a solderless banana plug. It's meant for the wire to wrap around the metal just below the threads and get captured under the plastic cap when screwed down over the wire. The radio won't draw over 2 Amps, so you should be okay with this setup. Higher current than that might call for a...

The main difference between the receivers will be the regulator circuit board for the negative 9 Volts DC. Found only in the original Mark 4, to power the horribly-obsolete "poof" chip, the 1302 ROM in the transmitter. No need for it in the 4A, since the channel selector/PLL run from 11 Volts...

Electrolytic capacitors are the suspects in this murder mystery. They will be marked for polarity. Some will have a "+" at one end, usually the end with rubber around the lead wire. Other caps will be marked "-". Naturally the plus side is the other end. Make a careful note which way the part...

Bought one of these recently from Ali Express. The test leads were already assembled. A real necessity checking high-voltage transformers for insulation problems. 73

Turned into a part-time job on the CB Tricks forum back in the day. A couple dozen signups or more a day. Got to be tiresome. 73

Can't remember if that's the one with plastic screws holding down the two audio-power transistors. We adopted the habit of putting a 1N4001 rectifier diode in parallel with the thermistor "TH" in the schematic. The cathode of the diode goes to ground. Found that this prevents the audio...

Most of the lightning-surge damage we see enters the radio by the power cord. If you see this, there may be multiple faults from a surge this size. This one was only a little more subtle. Popped the disc cap in half, rather than scorched it. The flash burn under the line-filter board...

Some days cleaning up at my shop feels more like archaeology. Here's a sign a former tech put up after a customer zorched the finals in his FT-101. The other one cracked, this one only cratered on one side. About 30 years ago. Get glass hot enough and it gets soft. A stab from the past. 73

Probably more than one. Would be cool to figure out which fixed resistors to sub with potentiometers. Might be tuneable that way. To do it with fixed parts you'd have to work out the new component values. Have fun with that. Not on my bucket list. 73

Just re-capped the mobile version of the Console II. AM receive had been poor, but sideband heard mostly okay. Sideband transmit audio was very low. New caps fixed both issues. Lordy that radio has a lot of them in there. 73

Capacitor value depends on the circuit. In some, the larger cap makes no difference that you can see or measure. And in some circuits you'll disrupt an intentional time delay. 73

The very first caps to fail from age alone are frequently the ones rated for six or ten Volts. Around here we call that the "Ten Volt Blues". Manufacturing techniques have shrunk the size many radial caps found in a 45 or 60 year-old radio. We don't stock but one or two caps with a voltage...
