A bit more about putting a hand in your pocket while checking high voltages. What is really dangerous is current across your heart. By keeping a hand in your pocket, the charge will typically run down your arm, down the same side of your body and out to ground. Great advice and a great video.

[@geofgibson]

Great demo. There’s also an Old School tool from ham radio days sometimes called a chicken stick. AKA voltage discharge tool. Stew Mac sells an affordable one and you can make your own. It gives you a more stable tool with longer reach. One thing she didn’t mention was the power value of the resistor. Note she’s using a 5W. Keeping in mind P=V^2/R, dissipating 100V in a 1K resistor will still be 10W. You won’t smoke the 5W resistor as that is not continuous power, but... if you happen to be discharging 300V and you have a 470 Ohm resistor, it’s gonna get hot. Go for a reasonably large power resistor and I wouldn’t go less than 1K myself. Not trying to be over critical, but you can’t be too safe with high voltage. And keep that other hand behind your back. Wear insulated shoes, too. Not like me who walks around barefoot all the time. Feet on concrete is a surprisingly good conductor.

@@TempleGuitars Thank you for the kind comments. You obviously haven't watched very many KZbin videos. All I did was state two facts: one she is pretty and two she isn't a ding dong, she actually appears to know what she is doing. The comment was not based on a sexist perspective but on my experience with videos on KZbin. To be fair, sometimes, male or female, the poster doesn't know or can't explain what they are doing. Forgive me for stating another fact and that is the guitar/amp trade tends to be dominated by men, some who don't know or can't explain what they are doing. It is unusual to see a women who is knowledgeable in this, perhaps unfortunately, male dominated business. I didn't say a women couldn't or shouldn't be such. Further, If I was all that concerned with protecting or projecting my "macho" "sexist" sensIbilities I wouldn't have stated my fear about working on amps until I watched this excellent female produced and provided video.

Hey, I'm currently restoring two TEAC A4010S reel-reel tape decks and getting my "feet wet in vintage electronics so to speak". Built my own Dim-Bulb circuit tester to make sure they were safe to plug in with no short circuits and had healthy transformers. ( having a variac would of been good also). Just wanted to stop and say I found your video really enjoyable and loved seeing your electronic workbench. Solid state amp repair is fascinating, and I've always wanted to get my hands dirty on some vintage high voltage warm tube based equipment. Found this video from using google search on the topic of discharging capacitors, it was very informative and to the point. I chose a 5W 100K Ohm power resistor heat-shrunk to some 14 gauge red wire with two metal hollow ferrules soldiered and heat-shrink to the ends of the wires. I imagine a lot safer than discharging electrolytic capacitors and CRT TV fly-back transformers than with a rubber handled screwdriver and gloves. =/.

[@stuffoflardohfortheloveof]

That was very good. Anything like this always takes me back to roughly 40yrs ago when I was studying electronics in college where, using only mA ,we were taught to discharge by using a screwdriver across the leads.....of course, being a guitar player, I decided to build my own amplifier and, sourcing the instructions from something like ‘practical electronics’, went out and bought all the components.....some of which were electrolytic caps and a mains transformer, tapped to supply 6A (I think)......anyway, long story short in my enthusiasm I forgot that I wasn’t in college using mA and proceeded to discharge with the screwdriver.....my whole world turn green and blue for a while! 😳 taught me a painful, but valuable, lesson 😀👍🏴󠁧󠁢󠁷󠁬󠁳󠁿

I just found your videos, very nicely done!! I learned long ago in an electronics tech class about discharging caps safely, and working with high voltage safely. I work with high voltage RF circuits in communications equipment as well as old audio equipment and you'd never make the mistake if bumping a "HOT" capacitor charged to 3000 to 5000 volts in a RF amplifier circuit more than once!! You might not get the second chance!! Glad to see you teach proper safety methods and testing. Properly designed power supply circuits usually have bleeder resistors across the terminals of the caps too but they do take some time to bleed off. I'm glad you mentioned using a bleeder cap when draining. you must have had some good instructors or mentors! Keep up the good videos!!

Your Fluke 114 has an "AUTO-V LoZ" Setting. In that mode, the meter has a low input impedance, in your case about 3kOhm, if i'm correct. The manual should give more details. So you can discharge your capacitors using the DMM in AUTO-V LoZ and monitor the discharge process at the same time, and you don't need any extra equipment to do so. This function is also handy to get rid of ghost readings.

[@bill-2018]

When I make power supplies of around 250/300 Volts I always add a 220kΩ half Watt resistor from the capacitor to earth. It only takes a few milliamps but then discharges the capacitor after switching off quickly enough that by the time you get the cover off the voltage has decreased dramatically. Higher voltages might need a larger value resistor to cope with the increased voltage. However don't trust it and still check with a voltmeter in case the resistor has failed. None have failed yet. If there is still appreciable voltage do discharge it as seen in this video.

[@GonzGunner]

Colleen, I have watched all your videos to date, and I have learned so much from you! I like how you state what an amp symptom is, how you diagnose the problem, and how you describe the method to fix it, with all the things that also need to be done. You cut through the BS of most of the other amp techs I see here on KZbin, I mean, how long should a viewer be made to suffer just to see the UNBOXING of an amp?

Hello Colleen. Very good tutorial on discharging caps for safety. I remember my first AC/DC THEORY class in college.

I really liked how you explained what is what and what you were doing on this video! After I'm done with this comment, I'm going to watch other videos from this channel and I'm looking forward to see more!!! P.S. When I was in high school, there was a year where, for 1 month, once a week, we had 2 hours where we worked with electronics/electricity, then, the next month, we learned about cooking, then about being a hair dresser, working with metal, then with wood, etc... The idea was to make us try out different things to see if there was something that we really liked, to help us decide in what direction we would like to go. During one of those months, we worked with electricity and I remember our teacher saying that when you're working with high voltage, it's always a good idea to keep one hand in your pocket, the reason being, just like you said, in case we get shocked, keeping one hand in your pocket will make the electricity go down, from your hand to your feet instead of going from one hand to the other, through your heart and risking having a heart attack.

WIthout thinking, I put my finger on the fuse holder, touching the 2 leads and completing the circuit (bypassing the fuse). Then, a portion of my finger flesh exploded inside out in a cloud of smoke (smelled like burnt hair). No blood came out, as the wound was already burnt... That was my guitar playing for that year... And I was lucky I got away with just that... I never messed up with my amp without a multimeter ever since.. :D SO, guys, take it seriously!
