played a lot in the late 80's early 90's and was shooting in the mid-70's when I quit because racing mountain bikes was more fun. Was invited to a scramble tournament in 2001 in San Diego and despite me not playing for nearly a decade I shot a 75 in a practice round and our team won the...

mine wasn't a resistor. Just two jumpers. Can you post a photo? What's the value? Is it possible that it's a 0R resistor? Some manufacturers use them in place of wire jumpers if the boards are machine populated

with all the requisite warnings...I'm not an engineer, do it only if you can safely use a soldering iron, make sure it's unplugged... this is how I did it. The top drawing is as-wired for 220V. The two loops in the xformer are in series. The bottom drawing has the jumpers (shown in pink)...

I rode them extensively over a couple of year period. When I took my bike back to the east coast where the trails are relatively technical and the speeds are slower, they excelled...gripped everywhere on every surface and it was an amazing experience. Out here in OR, the hills are longer and...

I tweaked the power supply a little bit by adding some resistors parallel to ones between the filter caps so it wasn't dropping as much voltage. B+ is up to 320V from 234V and it's a lot more touch sensitive now. Before my tweak, the plate on V1B (the second gain stage) only had about 95V on...

about 30 years ago I screwed some drywall screws into every stud of a mud tire for riding on ice and snow. They worked great but also picked up many pounds of soggy leaves in 2013, I built myself a fat bike with 4" tires. It does a lot of things extremely well, super chunky tech trail, sand...

I've only recently started playing with the stereo part of this preamp and running through stereo FX and learned that there's a massive output imbalance on the FX returns and the FX send is hot AF and will clip all of my effects unless I turn the send knob all the way down. Swapping the tubes...

It can sound like a high pitched ringing when you play low notes, or possibly cause uncontrolled feedback

I don't know enough about it to give you a full technical breakdown of how it works, but my understanding is that there are cap/resistor combinations that can be put on the plates of the output tubes near the OT leads and they attenuate high frequency oscillations that might otherwise lead to...

I put a 630V 0.047uf cap across the terminals of the standby switch on the amps I built. Suppresses the pops

part of a snubber circuit to prevent ringing?

It's a pretty great material to work with and to ride.

Thank you. The truth of it is, I don't have the personality to make for an interesting channel and don't have the interest in editing video. I love seeing other people do it though. There's so much great information out there.

Thanks again. Couple things...It's been suggested to me that I'm on the autism spectrum. I've never been tested because I don't see the point in knowing, but I can't rule it out. It's possible that one of the ways it shows up is that when I get into something, I get REALLY deep into it...

Thank you!
