Hello, steemians, and welcome to my page, eh!
Today's post is a continuation of the process of rebuilding an old tube amp into a guitar amp. My first post dealt mostly with removing the unneeded circuit parts and the old power supply filter capacitors. In this post, I make a couple of modifications to the metal chassis as part of the rebuilding process.
Let's take a look at where we left off last time. This is the point where I start adding parts into the build.
In order to accommodate the new power supply filter capacitor can, I had to cut a hole in the chassis to mount it through. I took the amp to the workbench in the basement and cut the hole in the chassis with a hole saw. I don't have any of the hole punches that the custom amp builders have for making holes, they're too expensive to have around for just occasional use, so I use hole saws for the job.
The next thing to do was to make a backplate to cover the holes in the back of the chassis. I used a piece of a galvanized strap normally used in constructing roof trusses and such, I cut it to length and then drilled the mounting holes.
Here's what it looks like from the inside when it's mounted on the chassis.
Next, I put the power supply capacitors in place and wired them up. In this picture, the power supply is almost done. I still need to drill the new holes in the back plate and mount the standby switch to finish the power supply wiring. The autofocus on my camera wasn't quite right on this picture. Comparing this picture with the previous one will give you a good idea of what got put into the chassis.
Here's a picture from the top of the chassis to show you the new power supply filter can mounted over the hole I drilled in the chassis. The hole in the chassis in lower right side of the picture is where the old filter can was mounted. Since the wiring setup is different, I chose to mount the new filter can in a more easily wired spot.
That's all I have for this post, I hope you found it interesting!
