British made Quad electrostatic loudspeaker's, famous audiophile-grade flat-panel speakers, famously used a crowbar circuit and a relay to short circuit the input audio to the speaker if the power exceeded a certain level. Tube amps could usually handle this OK but solid state amps often just blew up!
my desoldering gun came with a Nozzle Cleaning Tool, which is just a thin metal rod that you stick in to clear solder blocks. You can buy them separately and I highly recommend them.
I just recently did something similar with a zener diode and a polyfuse (glorified PTC) on a PCB and I really wasn't sure if it would do the job, but glad to see it's a tried and proven design!
When the fancy desoldering gun fails, you go back to the basic plunger-type. It looks like a type Radio Shack used to sell, I liked it because the tube was aluminum and not plastic. Plus you got it at a good price. Still have mine to this day.
Fran, my 1990's era Hakko desoldering station at work died about 4 or 5 years ago and parts aren't available, so I switched to an AOYUE (pronounced Eh-You)) desoldering station, which I quite like. The tips have an integral metal tube or pipette several inches long that passes all the way down through a long heating element and into the collection chamber, and that tube is well-heated along it's entire length so it almost never clogs up on me. If it does, I can just pull the solder collection tube off and touch a regular soldering iron to the metal pipette that carries the solder into the collectiin chamber, and within a few seconds I can shake the gun and the solder that was forming the clog will have been liquefied and will fall right out. AOYUE are surprisingly affordable, and the US importer is in Massachusetts.
With that crowbar, no headcrabs allowed! Nicely explained. I like the idea of using a PTC, should not just save the pedal, but also the power supply... unless it's utterly dodgy. All this while not posing as a pesky little voltage-limiting resistance bugger in normal conditions! Nice. Basically same thing as a dim bulb tester, and to anyone who might not know, a light bulb is a PTC resistor too. Nasty leak indeed, but still a thing of beauty and a joy for ever. As for desoldering, I either use a solder sucker or just a blob of solder and quickly heat the legs up, pull the part out. Works OK with DIP8 but not really with 14 or larger. IC sockets never failed me, but then my devices are not used in moist conditions. Tube sockets, on the other hand... meh.
I wrap 9 volt batteries in kitchen cellophane wrap (Cling Wrap, Saran Wrap etc) to contain leakage and protect expensive pedals, multimeters etc from damage.
What is the type of the thermistor used in the crowbar? BTW, it's an amazing idea to have these Frantone videos on this channel, much easier to find them for reference!
Nicely engineered... But @18:23 ?? 🤔Are you saying a fuzz box is a LINEAR circuit? Analog certainly - but linear? Surely its controllable non-linearity is the whole point! 😄
Not a chance - Fran stopped doing repairs for others many years ago, unless it's a Frantone pedal or a project she considers very interesting and worth pursuing.
I love watching you fix stuff. I am stuck at home with mild Covid. How could the effect get excessive voltage problems if the power source is a 9 volt battery?
it can't....the problem occurs when a user plugs a power supply that is too high voltage, reversed polarity, or both of the above into the external power jack of the pedal.
@@m.k.8158 But the "power supply" in my understanding is the 9 volt battery. How do you "plug into a power supply that is too high voltage, etc when the power comes from the aforementioned battery?
@@alanlarson9219 You also have an option to plug in an external power source, for things like a full day of use in a band, or if you are doing a tour, and do not want to have the worry of a battery going flat half way through the night. So you will either plug in external power, as being a band you probably have sockets out on the floor to power things like speakers, effects racks, lights and keyboards already. Or you have to change the battery every single night just before the gig, with a high risk of forgetting, or putting in an old one, or trying to connect it poorly.
TheDC barrel jack has a third contact that is normally connected and disconnects when you put a plug in; it's typically used for an internal 9V battery. So, the pedal defaults to battery unless a power supply is plugged in - then the battery is disconnected. Get well soon!

Whenever I see a Frantone video, I can’t help but think of Lou Reed.
I enjoyed watching the repair.

Your stuff is always built the way everything should be!
And a merry fuzzmas to you 😍

They don't work when the solder solidifies in the tube high up neat the container.

Aoyue, WEP, Yihua, Baku and other Chinese soldering irons and stations - different brands, same OEM, they do the job.

Really going to enjoy these videos. Love your repair videos.
Good Jahb!

Thanks for lesson Fran, if I could hit the like twice I would.
Love your videos! Need to buy some of your pedals now!
great video

It's a 10k ohm PTC (Positive Temperature Coefficient) thermistor
beyond the unheated tube, would you recommend this desoldering gun?
also: i adore how this pedal sounds with the tone control dialed down, reminds me of some of Earth's middle albums, maybe Pentastar or Hex
Someone just like myself that knows what there doing you go fran

Any chance you could fix a couple of my pedals :( Not Frantone pedals, but what a great way to fund your channel! 🎉. 🤓

Fran really should find a way to make pedals again.

Jealous of the shirt.
