I built this stereo pre amp to use with my Stereo effects unit. Temporarily uploaded here until his site is back up. The present circuit can deliver 10W of output power when driving an 8 Ohm load, or about 18W 4 Ohm. Mouser Electronics great source for many parts! The use of squelch device is somehow unique, possibly put there to tame hiss and noise during quiet passages between notes. A high quality automotive subwoofer system can be assembled in cheap price. Kurt began playing guitar at the age of nine in Kalamazoo, Michigan.
For some the Fuzz alone might not be loud enough, this can be fixed by raising the value of the 820 ohm resistor and lowering the 39k one. The schematics on this page are provided strictly for educational purposes. Notes: This is not a kit, it's a one of a kind personal project that I created from scratch. It is a pre amp that I used for recording. Trainwreck Various notes on the Trainwrecked Expresso design Several interpretations of the Trainwreck Express More Trainwreck Schematics in the Archives! Additional subsonic filtering action is provided by C1 and C2 at the inputs of the crossover circuit. It is not a stomp box distortion pedal. Waltzingbear's Pro Audio schematics Vendor Sites Allied Electronics aNaLoG.
The two 50K pots which have their wipers connected by resistors are wired so that as one increases, the other decreases, giving a pan from one point in the circuit to another, probably changing the amount of distortion. Follow along with the instructions below by referring to the. Guitar amps with tubes are currently front and center in the high-end market because many guitar players find their sound characteristics to be superior to solid-state amps i. See the Hoffman Board Information section at the top of the forum for more ReVibe info. There is a link to the Adobe site on the index frame to the left where you can download the appropriate Acrobat reader files for your computer. More Fender Schematics in the Archives! Use the Hoffman layout diagrams, parts listings and assembly instructions found on this page to assemble these boards. It puts a pair of series-wired speakers in parallel with another pair of series-wired speakers.
That's why I do the test builds first. Filter caps can hold a charge that can give you a severe shock. In some cases you need to have major fabrication skills to build these projects. In other words, a low impedance speaker is a big workload for your amp and a high impedance speaker is a small load. Good for single note and leads. This topic on my amp forum describes how to print 8.

Furthermore, nowadays we can do without the old-fashioned Vib-Trem feature frequently included in those designs. Following is the schematic diagram : The inputs through Q1 form a differential summing amplifier with switch S1 functioning as a polarity inverter. It can happen that the protection can be too sensitive, in that case certain adjustments are admitted in the value of R4 or thermistor. They all probably germanium devices. Pedal 2 was a much better layout design.
Very similar to a Fender Champ 5F1. Just unplug the amp from the wall and keep strumming your guitar until the sound dies away. Solder your pickup leads to the pigtails after installing this assembly Solder your pickup's hot conductor to the pigtail inner conductor and solder your pickup's ground wire to the outer shield of the pigtail. There are also many books on the subject of tube amp circuit theory, design and building that you can read to help make your first build of boutique quality. While tubes are no longer the technology of choice in the computer industry, they are very much alive and well when it comes to modern high-end guitar amplification. You will find a large community of friendly amp builders at the link above. Bogner Bogner Triple Giant preamp section Bogner Triple Giant preamp section Notes on Bogner Triple Giant circuit Bogner Ectasy More Bogner Schematics in the Archives! I like Rack mounted gear because it takes up way less space, the knobs all face out, you don't have a bunch of gear sitting on the floor, and it's easy to wire it all up using short George-L cables.
Find a Fender schematic and its related layout drawing and start making a parts list. There's also info on my personal stuff, photos' etc. Please go to the for technical questions. A twin T-oscillator circuit drives two bipolar transistors to load the signal down after it is amplified by a single input stage. This is where you go to ask tube amp questions. For example, the diagram below shows you how you can turn a pair of 8Ω speakers into either a 16Ω or a 4Ω load.
Things always change after I do a build. Open the drawing with your favorite drawing program. For example, the diagram below shows a 4Ω cabinet containing four 4Ω speakers. Servicing Fender amps How to's Charts and Diagrams The links below lead to wiring diagrams for the transformers I have sold Older discontinued models are here also This section has info on the Hoffman amplifiers that I used to build many years ago. The Kay Model T-1 Tremolo is a very simple circuit. The cabinet impedance depends on how the speakers are wired and may differ from the impedance of the speakers. The diode and transistor types are unknown.
This is a post on my amp forum This is not one of my mods This is my Fender amp servicing guide. If you are thinking of building this, copy pedal 2 layout. Photo pages and diagrams I called the early metal box 50 watt heads the 2034 model I scanned the Metal template that I used to make the 2034 circuit boards Here's an image of that metal template scan Here's a.
