'62 Brit-Plex 45W Amp Kit

About This Item

The original British powerhouse that shook the world
When this amp launched in a tiny London club in September 1963 it changed the world, and we still can’t get enough.

Favored by blues and rock players for its exceptional sustain, the '62 Brit-Plex is chock-full of harmonic gain, with a thick but focused midrange that refuses to get sloppy or lost in the mix. Put this head on a classic 4x12 cab and watch out!

Just listen to the raw power Angus Young gets on "High Voltage" to hear how commanding this amp can be. The '62 Brit-Plex is the original sound of classic rock, and has a virtually unlimited suite of tones that can be dialed in with ease.

StewMac has lovingly recreated this timeless amplifier in our '62 Brit-Plex Amp Kit. This is one of our Icon Kits: modern reproductions of vintage classics.

Take your amp building skills to the next level with this kit. The ‘62 Brit-Plex is a perfect place to get serious about amp building. This is an involved amp and will be a fun challenge to complete.

62 Brit-Plex 45W Amp Kit Build notes


Verified Buyer

This was fun to build for me. I've built a dozen or so 500 rack modules and this was certainly easier because of it's size. The instructions are very clear and concise. If you follow them precisely you should have few if any issues. A couple of suggestions as follows: When you are instructed to install the front plate, try to leave it off until after you build the two input jack assemblies as it is pretty easy to leave soldering iron tracks on the plastic plate. I may have to order another plate as I nicked mine when my soldering iron cord snagged on the chassis and brushed the front plate.

Also the instructions say to solder all connections last on the turret board but I found it much easier to solder the sections that you build after you place the components and jumper wires as you complete each section. Check each section carefully to avoid errors and proceed slowly. I also added about 1/4 inch to the suggested wire lengths to make sure there was enough. Most of the time the added length helped out. You can always shorten them if you find it better to dress the wires out later.

On last thing: remove the springs and retainer cups on the large tube retainer assemblies as they can get beaten up from all the chassis flipping you have to do Just mount the lower parts to the chassis. That's it. I had 1 error where a wire broke off from a nick when I stripped the insulation back. Using an xacto knife carefully worked the best for me to strip this solid wire. Also I have a lot of experience stripping wires as I was an electrician for 45 years.

Best of all, this thing sounds GREAT!

This is the second amp kit I have bought, and found the entire process very enjoyable. Product and instructions were excellent. Perfect for the organized and detail-oriented builder.

First amp ('65 P-Reverb) performed fully as expected (I have not finished the second project yet), with promised sound and performance for a 'new/classic' amp of the '60s era. Very happy with results.

As a bonus, I have gained enough knowledge to repair simple amp problems that have occurred on new store-bought amps. Never would have attempted it without having done the kits.
