London Power’s kits allow the hobbyist or amp builder to add features to an existing project or to build a new project from scratch. Each kit contains the circuitry relevant to itself. For example, a preamplifier kit contains the circuitry that makes up the audio signal path ONLY; the kit will require a power supply […]
Tube Guitar Amp Books (and more!) by Kevin O’Connor Browse our Tube Guitar Amp Books In electronics and audio design, many circuit methods and topologies are available for any given goal. Most books present a single solution to a design problem, but Kevin O’Connor’s books offer many possibilities. Justified Approach It’s nice for a builder[…]
The Cutting Edge of Power Scaling Technology from the Inventors of Power Scaling Selection Guidelines The first selection parameter is how the amplifier is biased: cathode bias or fixed bias. In general, this resolves to the following kit requirements: Fixed bias: SV1 + RBX Cathode bias: SV2 + VCK Switchable fixed/cathode bias: SV1 + RBX[…]
Learn about Power Scaling from Its Inventors Browse our Power Scaling products. The newest term in Power Scaling is “Super Versatile” (SV). Our SV-range of Power Scaling kits represents a breakthrough in performance and value, combining the sophistication of our former “Super Flexible” kits with the cost-performance of the “Super Budget” kits – so SV[…]

What is Power Supply “Sag”? “Sag” is a well-known power supply effect caused by resistance in the supply and variable current loading. As an amplifier pulls more current from the supply, the supply voltage drops, or sags, and this can cause a compression effect. The transient or attack portion of a note is “squashed” or[…]
Switching Kits by London Power – Human-Scale Technology London Power‘s range of switching kits allows the player, hobbyist or builder to access amplifier channels, amp features and system configurations, using simple circuitry. All of our switching circuits are discrete so they can be repaired by anyone with average skill, and can be maintained for decades[…]
Which “The Ultimate Tone” Volume to Get First? TUT – The Ultimate Tone, is an ongoing series of distinct books about guitar amp technology with a heavy focus on tube circuitry. Currently there are six volumes. You can buy the whole series as a package (TUT-DEAL) or buy just one or two at a time.[…]
London Power‘s line of pre-built equipment for studio use is produced to order on a short turn-around cycle. All units are hand assembled and hand soldered, and then rigorously tested and burned in. Because this takes time, we prefer to discuss the needs of each client prior to accepting the order. Contact us at [email protected][…]
