A tube radio

A tube radio is an old type of radio that used a vacuum tube and focused on playing music. They were also called valve radios and they became popular in the early 1900s. Most of these radios operated with a tube as the detector, which made them more expensive than other types of radios at the time. A common example of these types of radios is the 1937 Zenith GR2, which was one of the first radios to be sold by Sears Roebuck and Company.

A speaker

A speaker is an audio driver that converts electrical signals to sound. There are many types of speakers and they each specialize in a different sound frequency range: Subwoofers, tweeters, and woofers are just a few examples.

This tutorial is fairly simple, so the only tool you’ll need is a drill. You can use any drill with a 1/4″ inch bit. If you don’t have one, they’re relatively inexpensive and many hardware stores sell them in packs of 4 or more.


This is a good idea as you want to make sure that your amp is able to function properly. You should also make sure that you have the right sized speaker so that the sound comes out clearly and easily. If you don’t, then you should replace it with an appropriate size.

A speaker

A speaker is a device which converts electrical impulses into sounds. It widely used to amplify the sound of an audio signal and is therefore a part of most electronic devices that produce sound.

Choose a tube radio for the conversion

For this project, you’ll need a tube radio. The older tube radios are better because they can be used with guitar pedals, but newer radios will work too. You’ll also want to make sure that it has an aux input for your guitar.

Find the amplifier

First, you’ll need to find the amplifier. This is the piece that will power the sound through your speaker. It can be found at any synthesizer store or online. If you don’t know where to purchase one, check out this website for a good deal on an amplifier.

Once you’ve got the amp, plug it in and turn it on so it can be ready to use later when you’re finished with your tube radio conversion.

Make the guitar speaker

One of the first things you’re going to need is a speaker. These can be found at any hardware store or even on Amazon. You should also buy a 4×10″ speaker cone, a 10″ metal grille, a 2″ voice coil, a couple of 1/4″ phone jacks, and an old phone jack cord.

Create the tube amp head

Next, you will create the amplifier head. This will be by far the most time-consuming part of this project. You’ll need to cut your plastic bottle in half and then glue it together to form a cylinder shape. Make sure that it’s big enough for your speaker to fit inside without too much wiggle room.

Add electrical components

The next step is to add all the necessary electrical components: two wooden blocks for feet, two power tubes (12AX7), and two preamp tubes (12AT7). These can all be found at your local electronics store or online. Once these are added, solder them in place and wrap them with electrical tape so they don’t move around while you’re working on other parts of the guitar amp!

Cover with fabric

We’re getting close now! The last step is to cover your amp with fabric. You’ll need both foam fabric and wool felt sheets in order to get this effect right. First, glue together strips of foam fabric into one long strip and wrap it around the tube amp like an accordion-style design until all the cre

Wire everything together

The first thing you’ll need to do is wire all of the components together. This should be a relatively easy process, thankfully.

Start by removing the old speaker from the tube radio. Then remove any scrap metal from around it that might have been left over from the original installation process. Be sure to just bend these pieces out of the way and set them aside for now – you’ll need them later on in the conversion process! Next, install a new speaker just like you removed the old one. The wiring for this should come with your new speaker, so refer to that if you’re unsure about what wires go where.  Now connect all of your power cables, including battery cables and transformer cables (if needed).

Preventing feedback

First, you will want to check for feedback. Feedback occurs when the sound from the speaker reaches the microphone and is amplified back. You can do this by opening up the radio and sticking your ear up to it. If you hear any sounds that are not coming from the amp, then you have feedback.

If you notice you have feedback, there are a few ways to solve this issue. One way is to make sure your speaker is not touching one of the main components inside of the radio. Another way to avoid feedback is to make sure your amp is not too close or next to any speakers or computers.

How to convert a tube radio to guitar amp FAQS

Can I use any speaker for this project?

You’ll need to find the right size of speaker for this project. It should be small enough to fit inside the tube radio’s metal frame and still vibrate freely.  A good place to look for one would be eBay or second-hand shops.


Turning tube radios into guitar amps is a great way to get your hands dirty and make something new. It’s also a great way to contribute to the ever-growing movement of recycling and reusing old things. Not only can you enjoy playing your guitar with your friends but you can also show off your handy work.

The first step to making a tube radio into a guitar amp is, of course, turning it on. This will allow you to test out the sound quality and the volume levels. Some radios have a “test” button that can be used to turn it on, but other models may require a bit more tinkering.
