6AS7 SET amplifier with JAN 5R4 rectifier tube

This compact amp is based on an 6AS7 (dual triode), JAN 5R4 (both coke bottle) and 12AX7 driver tube. The top plated is sprayed to match the Edcor OPTs (1.7k/8ohm). The base is solid Mirbeu. Power transformer is Hammond and so is the choke. Component-2-component wiring with no PCB. Silver wire connects gold RCAs to the driver tube. Jensen (0.22uf 630V) copper paper and oil caps join the driver and power stages. The 6AS7 are pushed to 13W dissipation. Bass is heavy and extended, mids and treble highly detailed and sound stage very deep and defined. An extremely good looking and great sounding amp.

Additional information is available in the 6AS7 tube amp from layout to listening forum thread.
