NOTE: Review is early, pre-tweaks version.

Why has the price increased?
Beezar has been selling the Torpedo at a loss since the beginning. We did this because the amplifier persisted in a slight power supply noise (hum). With the latest tweaks (included in all kits), the Torpedo is completely noise-free and with the E90CC, is superior to many higher-priced tube amplifiers.
This is it! The TORPEDO parafeed headphone amplifier. ECP Audio's Dsavitsk has created something totally unique in the DIY world of headphone audio. For the first time, a true output-transformer-coupled tube headphone amplifier completely designed and built with a PCB (Printed Circuit Board). Full details and building construction may be found on the TORPEDO website
or on Head-Fi.org in the Dsavitsk/Beezar Torpedo Build Thread
The ECP AudioTorpedo uses a unique aspect ratio and a custom Beezar/Context extruded and machined case as the basis for its design. This minimizes potential flux interaction between the power and output transformers and gives the amplifier its unique "Torpedo" look.
In another stroke of genius, ECP Audio designed the parafeed tube amp to utilize the ubiquitous and truly inexpensive 6J6 tubes ($2 and sometimes less!). In the same family of tubes as the 19J6 used on the famous Starving Student Millett Hybrid (SSMH), the 6J6 tube and its equivalents exists in the tens of thousands world-wide. Unlike the SSMH, the Torpedo design will not run out of tubes! Besides the 6J6, Beezar will even stock two more tubes that are functional equivalents for tube rolling in the Torpedo - the 5964 and 5844. Beezar has over 1,500 tubes in stock for the Torpedo! There are many, many other tube types that will work, too. Refer to the Torpedo website
for a full list.
More recently, Beezar has discovered the 5920/E90CC tubes for the Torpedo. These tubes place the Torpedo at a higher level of performance than any 6J6-variant. Detail is greater and background is blacker. We have not found a better tube to put into the Torpedo.
Please note that the Torpedo's PCB, custom-wound Edcor transformers, and the Beezar/Context custom-machined, black-anodized, and laser-etched
case are not available anywhere except at Beezar. The case is particularly unique because it is extruded at a special 14" length that is not standard stock.
Note: The Torpedo can be easily configured for 120V or 220V supply. Because of that potential choice, Beezar sells both US-domestic and European standard power cords with the kit. Please be sure to make your selection below for the correct power cord that you need.
The Torpedo Full Kit includes the following:

This amplifier is a true tube amp and runs at typical tube voltages. Voltages exceed 200V inside the amp. Neither Beezar LLC and its subsidiary, Beezar.com, nor ECP Audio (ECP LLC) are responsible for improper construction. Instruction for the correct and safe way to build and operate this amplifier are shown on the Head-Fi.org thread referenced above and at the Torpedo website.
