2.2 ohms ESR!! 🤯🍿Man I need to start looking at my old gear ... thanks for video!
me too, I feel like I need to take everything apart especially some old stereo receivers and things from the 70s and 80s.
That power supply I bought about 10 years ago and who knows how long it was like that.
I was watching some guitar amplifier repair videos and there’s a certain capacitor bank circuit board that gets used in several fender amplifiers where they use cheap ones and they leak visibly within a couple of years.
@@GadgetReboot Despite my studio and electronics lab being packed away in storage, I think it is time to set up the electronics lab! I have two Xboxens that are in danger of a leaky smoothing capacitor for the clock. The clock is no longer necessary and those caps have been said to ruin some boards. The funny part is reading the comments where people become seriously offended at non-trained people merely cutting the caps out 😆if it works it works, but I will look into actually replacing mine since I now have the proper tools!
I also have three DC distro boxes that I built and I might do a video talking about them and discuss the designs and things I seemed to have gotten right and wrong. Two still work and I have very few ground loop noise issues using them but another bit the dust when I "requested" it draw more current than the PSU could handle. Thankfully, none of the SIX Roland Boutiques being powered by it suffered any damage (one or two of which are even discontinued).
I had a 200 watt bass cab and metal zone pedal as my only signal chain for over 20 years haha. The pedal actually costs like 30 dollars more now because of the waza circuit changes you van turn off and on. You could waterboard me and I couldn't tell you what happened to that amp hahaha
Awesome content. I have a curve tracer and some tesla germanium parts along with expensive audio poly caps I'm gonna send ya. I'll send you a variety of expensive opamps too. I have more than I will ever use or do justice to the fortune I wasted buying too much. As a way of thanks. I need your po box number again buddy. It's the least I can do. You're a good man and done me a kindness recently that I appreciate. I won't buy you in leds, I've given over half of them away.
I have the vintage ones in a safe place haha.
The metal zone was the first thing I bought when I got the first guitar in 98. Even before I bought a pick because the store gave me one pick with the guitar purchase.
I got rid of that guitar maybe 15 years ago but I can’t have a pedal collection without pedals.
@@GadgetReboot I only recently lost mine but I can't recall where to save my life. It sounds wretched compared to their other distortion pedals ehh. I played alot of blazing fast Norwegian blackmetal growing up so it sounds like a wall of noise with my right hand going back and forth at obscene speeds. I can't stomach it now but it's so fast on your picking hand that it gave me dexterity that I never thought I'd achieve because it's easy to fret but played blazing fast haha. Mountains of might by immortal was like a marathon to play when I was young. So sweaty I'd have to change. Then I realized I just had to twich the tendon in my forearm while holding a 2mm pick. I'd sit in front of the TV and just drive open muted strings every night for years.
the heatshink would be better standing up, the heat needs to raise, the fins should be positioned to encourage the air to move by convection unless your going to add a fan. Again putting the lid on would reduce the efficiency even further.
The biggest problems with linear reg's is the voltage dropped across them and the headroom that you need just to keep them in regulation unless your using a LDO type. The upside is low noise and helping to heat the house in the winter. 🙂
if the thing was even getting warm to the touch I would probably go to the trouble of getting a bigger enclosure to go vertical but I just used the first scrap I could find for testing. I think I originally bought that plastic box in the 90s at RadioShack.
i remember hen we had RadioShack were in the UK, always good for the odd packet of bit's. @@GadgetReboot
if that cheap one used isolated DC/DC converters, there might be no hum
