300 Beast Tubelab

The 300 Beast is a 300B push pull amp that I designed and built several years ago. I still have the amp and use it often. It is based loosely on a design that appeared 45 SE Amplifier Bartola® ValvesJul 17, 2016 · The 45 Amp design. There are plenty of design circuits out there. I settled for a simple triode driver using a gyrator load. The choice was down to the 6J5 and 7193 (a military version of the 2C22). Both triodes are medium mu and sound really nice. Depending your needs, you may opt for a different driver (even pentode).

Voltages came in a bit high, even under load. The top row is the Tubelab SE in 45 mode, with about 25mA per tube. Meters are reading:660VAC winding, 520VAC winding, B+ at the filter cap. Bottom row is in 300B mode, running Shuguang 300Bs (not mine) at about 28mA per tube. First two meters got swapped:520VAC winding, 660VAC winding, B+. Electronics metarussWith the right iron, the Tubelab Simple SE comes to life. After a sanity-check with cheap Chinese tubes, here is the amp running with JJ 6L6GCs strapped as triodes. The amp sounds sweet with a bit more power than the Tubelab SE.. This coincides with the new speakers that I recently got off of Craigslist:a pair of Klipsch KLF-10s.

One is an unmodified 300B amp, and the other is set up like the picture above, with 6L6's. I need to design a low cost amp that outperforms the 6DN7 amp, works at least as good as the Tubelab SE with 6L6's, but costs less, and hopefully doesn't get shamed by my 300B amp.
