Once upon a time I bought this amp used in a pretty bad shape, but that was exactly what I wanted - tinkering with electronics is fun, right? 😆
One of the issues it had was a malfunctioning noisy crackly volume pot. Today I'll show you how to replace it if yours has this problem too.
Qué necesitas
-
-
If you're an experienced iFixer - it'll take you about 10 minutes to get it done.
-
Check the list of gear needed for this project. I offered the tools that I used but it’s absolutely doable with less or some other similar tools.
-
Important: disconnect an amp from the power outlet!
-
Please be careful - tube amps can hold a serious amount of electrical charge that can cause injuries or even death. Avoid touching any wires or contacts with your bare hands or instruments that have no reliable insulation.

Herramienta utilizada en este paso:Magnetic Project Mat$19.95

Next let's remove the volume knob - you'll need a flat 2.5 bit for that. Carefully insert the bit into the hole on the rear side of the knob to undo a tiny screw inside of it.
-
That's it - chassis is free 👍.
-
Hint: use a plastic tray or a magnetic mat to safely store all of those screws and nuts. You can even write where all those parts come from.

Herramienta utilizada en este paso:Desoldering Pump$3.99
-
Now let's replace a broken volume pot. For this we are obviously going to need a soldering iron, a flush cutter and a desoldering pump.
-
Hint - I used flush cutters to cut a broken pot off from the PCB and then used a desoldering pump to clean the mounting holes in order to get them ready for a new pot.
-
Also a good PCB holder may come in handy as you may see in my example.

...congratulations - you've fixed it 🏆.
