What is going on everyone. Not sure if you care or are interested, but there is an amp build series that is doing a giveaway, of a 5E3 type build. Check it out here: https://www.youtube.com/playlist?list=PLWSAHTeUhn0OeC9W01jhit7GwsYNRj909

10 to 1 it is the same value as the " good " one. Both devices are the same, both capacitors are the same, and the value numbers are sequential ( C134 - C135, R201 - R202 ). That resistor got HOT, so it very much changed the color of the bands. This pic isn't much better, but it is clear enough...

When you say louder, do you mean more range? This is a more unique tremolo stage. It utilizes a negative bias circuit driven by the 6SN7 ( I think that's what it says? ) to cause the 6V6 to oscillate. These are the three resistors I would mess with. The lower one will more likely adjust the...

Place that same curve next to a typical 12" woofer, and it will have a similar trace though. Most mid-band speakers roll off around 5khz. That's why a guitar sounds like a guitar regardless of what speaker you play it through. A typical instrument microphone has a pretty much linear response...

I have not put much effort into updating this thread mainly because all my time was spent building the amp and documenting it. I have finished the build as of Jan 1st and have spent the past week getting media done and getting ready to hand it off to the event coordinators holding the...

I am more or less an amp collector. I own six different amps, and I only have four cab options. Most of the cabs I own are inexpensive, unpopular, or something you would never catch me dead in public with. One is loaded with a quartet of G12T75's from the 90's, one is loaded with a pair of...

I have been commissioned to build an amp for a fundraiser where I live; which gives me a chance to VLOG another build series. I am gauging whether it is worth the energy to do another build series. Only for two reasons: 1. It takes about 2X as much time to do the build. And I never totally...

I am thinking of starting a YouTube series called Why You love it so much; a series about the amplifier of choice and what makes it tick. The hope is to allow you to understand why you love that amp so much. I am gauging interest in such a series and perhaps some help in direction and schematic...

So as I usually do, I randomly pick YT videos to watch. Many are related to electronics, as I am a guitar amp builder and electronics tinkering machine. It is often argued that PCB guitar amps are just as good as PTP ( Point To Point ) constructed amps; some may even say superior. I am in the...

I'm putting this here more as a placeholder and a way to force myself to do things I hate to do and hold myself accountable for creating content and media. Much of what you read/see here will be in future YouTube videos that I will link here and this will be a park page, if you will, for all the...

It is hard to get the level of drive needed without an additional gain stage in the path. If one tube is a phase inverter and the other is for the FX, that means only one tube creates 100% of the distortion the amp can make. There is no way to get the amount of drive the amp has with only two...

The height is for heat and aspect ratio. There is not much air movement in there and of course wood above that glowing glass. The Lo-cut is a cut only control, and the Hi-cut is a basic VOX style cut control. They are not interactive and you can use the Lo-cut as more or less a control to dial...

Nice!!! While I am not a huge fan of Morgan's build quality ( a little sloppy if you ask me ), but they do make some nice amps. The AC-20 was the only one that really ever called to me. My own amplifier design was in a way driven by the idea behind the AC-20. As I was trying every circuit I...

So I have been mulling around picking up a Two Notes Captor X for a while. My biggest fears of it are the likely short period of time before the thing becomes unsupported, or it simply gives up the ghost before I get any real use or ROI from it. After receiving it and the seriousness of the...

Where to begin? In 27+ years of playing and performing, I am always on the hunt for a smaller, better, more versatile rig. I was early to the lunchbox lo-watt game, but the biggest problem was lunchbox amps are usually single-channel, one-trick ponies. So I always have a 3 channel amp in my...
