Thomas Mayer Single Ended 300B Mono Blocks

Thomas Mayer has just completed another set of 300B monos with 10Y driver. As with few previous projects it is a four chassis design in classic portrait style. Each mono block comes in two boxes, as the amplifier and a separate power supply. You can spot, Yamamoto meter (showing bias current) Tango interstage and output transformers and of course ELROG ER300B output tubes.
