This amp circuit is derived from the classic single-ended designs that began in the 1930s.  Plug your CD player, turntable, wireless system, computer, cassette deck, or home theater system into this elegant circuit and enjoy eight watts per channel of beautiful listening pleasure.

The circuit can be used with a variety of different power tubes without modification (e.g., EL34, 6L6, 6550, KT88, KT77, 350B, etc). This amp is a perfect companion for our custom Horn Speakers, but can also be used with most other speakers.
