Kit1 300B/2A3 - Standard Edition We see this kit as the introduction to real Single-Ended Audio Amplification as it covers all the important aspects of design necessary: Single-Ended, No-Feedback, Class A, Directly Heated Triode, to become a member of this exclusive club of amplifiers. The Kit1 300B/2A3 Standard Edition is available in a number of configurations and hardware options. To make the choices simpler, we provide two base versions; STANDARD and SIGNATURE. This kit now comes configurable for either 300B or 2A3 operation. You simply specify which tubes you wish to be supplied with when ordering. We supply one pair but the kit can always be modified for either tube with about 10 minutes of soldering.

Kit1 300B/2A3 - PQ Edition The Kit1 PQ Edition now comes configurable for either 300B or 2A3 operation. This kit improves on the Standard Edition by adding extremely top quality Hi-B, double C-Core output transformers. Also included as standard are the Black Gate set and high quality volume pot. The Kit1 300B/2A3 PQ Edition is available in a number of configurations and hardware options. To make the choices simpler, we provide two base versions; PQ STANDARD and PQ SIGNATURE.

Kit2 6550 The Kit2 is able to produce around 12 watts in pure unblemished Class A, single-ended operation. It uses a single 6550 pentode per channel, one of the most popular and reliable pentodes ever designed in a single-ended arrangement. Each stage of the amp is operated in class A. As with most of our kits, the Kit2 is available with a number of component and hardware options.

Kit4 Push Pull Amplifier The KIT 4 is our introduction to Valve Amplifier Kit building. The circuit and power supply are mounted on one single printed circuit board, with two OTO - type push-pull output transformers, all mounted in a small P1SE type chassis. The circuit consists of two 6V6GT tetrodes running in Push-Pull class A, yielding about 10 watts, driven by a 6SN7GT and a ECC83 input stage. Easy to build, even for the beginner.
