SE6L6 Tube Guitar amp

6L6 single end head amp

" old trusty sonic box.."

Inspired by late 1950s Fender “Princeton” and “Champ” amplifier designs, I decided to construct a small and efficient single - ended head amplifier. This unique hand wired clean head is a "must have" amp for everyone. Single ended warm sound, reproduced by the preamp stage which utilizes a double triode 12AX7 / ECC83 tube in combination with a clever designed one knob tone stack section. The power stage utilizes the 5881 / 6L6 beam power tetrode. Optionally the EL34 or the 6550 it could be used according to your taste. The heart of this small monster is the unique designed custom output transformer. It has an exceptional frequency range response, that delivers tight bass, clean mids and highs. The power supply uses a custom power transformer, and high quality filter capacitors.

Costas Sarris was kind enough to let me try one of his little wonders, I'm so happy he did that! Now, I'm a working musician, I play tough and hard, electric blues. Guitar sound needs harmonics, tone, bite, character. His amp gave me the chance to travel from sweet and bold single notes to cutting and exploited double stops and all points between, really nice! To make it short, when you play the blues on the road, all you need is an amp to "hear" you, to feel your touch and express your deepest inner self...and that ain't easy. Costas' little amp made me feel like playing through an old trusty sonic box, I couldn't ask for more. Clear and gently or nasty and growling, this was a fantastic experience, Costas, thank you for sharing your work! "
