KT77 SE vacuum tube amplifier. Who gives who a black eye, single ended or push pull. Your choice!

This is a single ended KT77 vacuum tube amplifier that I built several years ago using 6SL7 drivers and a 5AR4/GZ34 rectifier. Trancendar TT-336 output transformers and a vintage Olson electronics T-318 power transformer.
