A new guitar amp build, part 3

in guitaramp-build •  3 months ago

Hello, steemians, and welcome to my page, eh!

This is part 3 in my continuing series on building a small tube power guitar amp. This amp should put out somewhere around 10 watts when turned up. Ten watts is a nice power range for practicing in a small room, or for recording purposes. This will be a fully functional amp with 3 tone controls and a master volume, so I should be able to get a wide range of sounds from it.

In my previous posts on this amp, I talked about preparing the blank chassis, and then mounting the parts on the chassis. At the end of the last post, I had finished wiring in the power supply parts and circuits. I still needed to install the power tube and preamp tube sockets.

After I got back from my camping trip, I started working on the amp again. The first thing I did was to install the tube sockets. From left to right on the picture, the preamp tube socket, the power tube socket, and the rectifier tube socket. The power supply transformer is the larger one on the right and the speaker output transformer is the smaller one on the left.

Once I had the tube sockets installed, I put in a connector strip and started the process of wiring the power tube socket.

Once I had those wires taken care of, I built the secondary power supply circuit. This supplies the voltage to the preamp tube. I also added a second connector strip to use for installing the parts for the tone controls.

After that, I installed all the parts that connect to the preamp tube socket.DSCN9623.JPG


It's starting to look a bit like a rat's nest inside the amp chassis now. That's pretty much normal for an amp that is wired using the "point to point" method instead of a circuit board for the parts. Some people say that the point to point method is better than the circuit board method because there's fewer wires to pick up electrical noise, but in my personal experience, I haven't found much difference between the two methods. How you run the wires inside the amp has a lot more to do with noise pickup than how many wires are in the amp.

The last picture is as far as I've gotten on the amp at this point. The next thing I have to do is build the tone control circuits, hook up the volume controls, and finish wiring up the power tube socket. Then the amp should be ready for testing.

Well, that's all I have for this post, I hope you found it interesting!

That’s crazy!! If I tried to make something like that I’m sure it would end badly!!! Ya gotta show us how it sounds after it’s finishes!


Once I get the amp done and tested, I'm going to make a short video to demonstrate the amp. I'm not sure when that will be, but probably in the next couple of weeks.

this is pretty awesome Amber!


Thank you!
It's certainly an interesting project for me.

Thank you! I appreciate that!

If i did that it would look like a rats nest. Great work! :)


Thank you!
Yeah, point to point wiring always ends up being pretty messy. :-)
