- Technical Details
Thank you for your interest in Weber Amplifier Kits. We would like for you to read the following information so you are aware of some of the issues involved with building an amp kit.
• We provide a layout and a schematic (on the Technical Details tab), but we do not include step by step assembly instructions.
• Troubleshooting advice can be found in the Kitbuilding Forum.
• Kits with cabinets ship as one complete shipment.
• Lead time for kits is approximately 2-3 weeks.
Please Read: The complexity of Weber kits ranges from very simple to extremely complex. We do not recommend anyone attempting to build any of our kits that are rated at 3 or higher in complexity unless you have the assistance of a qualified amp builder or electronics technician. Because of the sensitivities to wire placement, grounding schemes, and other parts related issues, troubleshooting the potential malfunctions and noises can be very frustrating without the experience and knowledge. All Weber amplifier kits have lethal voltages that are present even after power is removed. You must exercise extreme caution when working with high voltages. Before ordering any of these kits, you should look over the schematics and layouts provided for each kit to ensure there is enough information for you to feel comfortable building the kit.

"Hey guys, these kits aren't Lego™ sets. They require some thought, experience, and the correct tools. If you do not think you have the time, ability, nor tools to do this, maybe this isn't for you right now. If you still want to build one of our kits, but are a little uncertain, please enlist the aid of a qualified tech." -- Ted Weber.
FINE PRINT: Weber kits are sold only with the guarantee from the buyer, builder, and subsequent seller that no trademarked names or company logos other than Weber or the builders name will be placed anywhere on the kit. By clicking the submit button on the order form, the buyer is certifying his or her compliance with this agreement and guarantee. Failure to comply may result in legal action by the owner of the logo or trademarked name. Buyer agrees to absolve Weber of any legal liability which may result from noncompliance of the agreement.
Customer Reviews of 5E3 Amp Kit
Classic Tweed and then some!
Classic Tweed and then some!
Great kit for beginners and pros alike, and a great platform for trying out modifications and alterations to this classic circuit. Gave me a great place to start on my own amp ideas based around the 5E3, without breaking the bank. I also love the ability to have certain components not included, so I could do my own upgrades where needed. Makes it easier for the builder to customize, without buying double the parts. And of course, the 12A125A, and gorgious cab (I got mine in black tweed/british tan cane combo with a brown dogbone handle, a color scheme I like to call Macchiato) are second to none, both in quality and in tone. I’m sure this won’t be the last kit I build from Weber!
I’ve built a few amps previously from scratch. This was my first kit build. I used all the supplied parts, and it worked fine on initial power up. I think it sounds great, though I have no previous experience with the 5e3 to compare it with. On the advise of others, I will probably try replacing the tone caps with some of better quality, and change to JJ tubes. Will also try replacing the copper cap with a 5Y3 rectifier tube. And probably replace pots with something better.
I should have gone this route from the beginning to save myself some time, but I was curious how the different components compare.
I think the speaker sounds great. Great clean tones at lower volumes, beautiful overdriven tones as you turn up the volume. Lots of different tones available for just 3 controls. You have to play with it - the 3 controls interact.
Great platform for learning about tube amps. Many modifications can be done to this amp, though certainly not required.
Cabinet is beautiful.
Check out Rob Robinette’s website for lots of info about the 5e3.
TAKE YOUR TIME AND PAY ATTENTION TO LEAD DRESS.
I would buy this Weber kit again.
What a great little amp! This amp was a learning experience for me. I had built other kits but came up against some issues. First- this circuit has the characteristic of interaction between the two channels because of the shared tone control. I found a circuit that used a double tone pot and a few parts to isolate the channels successfully. Second- the screen supply resistor is under-rated and susceptible to burning out. At first, I just replaced with a 5W resistor. Later decided to replace the resistor with a choke. After some research, I learned that Leo added 470 Ohm screen resistors on later amps to improve reliability, so I did that. The tone appeared to not change but no more tube failures. I finished off the tweed with Minwax satin Honey Pine urethane.
