This is my version of a EL84 (6BQ5) Single Ended Stereo Tube Amp.
This amp produces around ~3 watts. This is not an unique circuit design by any means. Inspiration of this circuit is from the Decware, Budgie and RH84 amps with a touch of my own thoughts and perceived enhancements.

Specs:
One: 12AT7
Two: EL84 vacuum tubes (1 per channel)
Two: 5k Primary - 8 ohm output transformers (Edcore)
One: 260-0-260 ~100ma power transformer (Hammond 270DAZ)

The circuit shown is a mixture of topologies that I have built over the years. It is not unique and few will notice similarities between various circuits posted in tube literature and various DIY Forum/Communities. I do not assume any ownership of this design. This is posted for hobby use only. Feel free to copy, adjust and modify.
