- 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.

Well, this kit was a challenge. It was my 13th and the first one I had to send in to get it working right. I made a couple mistakes with resistor values and grounding and Weber helped me out. The challenges I faced, other than the mistakes, were several. First- this design uses an enormous number of filter capacitors in the power supply. The cap board is supposed to fit between the power transformer and the circuit board but is way too crowded. Second, the 3/4" spacers for mounting the board are too short, resulting in the board touching power tube socket pins. The impedance selector switch is large and touches power tube socket pins. So here's what I did: I made an epoxy turret board for the capacitors and mounted it on top of the chassis. Also made an epoxy turret board for the main board. I sourced a smaller impedance switch from Mojotone. in order to measure bias, I used 1 Ohm 1W 1% resistors from pin 8 to ground on the power tubes. Also used Orange Drop capacitors in the preamp portion. My mistakes were to use 470 instead of 470K mixing resistors which caused undesirable interaction between the channels, also made grounding mistakes since there is a preamp and a main ground. After it got corrected, it is a roaring beast. Hard to believe it is only 45W. It was a challenge and the experience helped me with my next project, the Natalie amp.
