211 A2 Amp

Circuit is 6sn7 voltage gain, the el84 cathode follower direct to 211 grid, in a similar fashion to Ongaku. The A2 driver is capable of sending the grid at least 40v positive, so peak power is just above 30w.

D3a Driven 2a3

The d3a is a great little high gm pentode to strap as a triode for use driving smaller DHT’s. Its not got enough grunt for a 300b. But it sounds wonderfull driving 2a3 or 45 (and if I could afford them the British output DHT’s). Valve rectifier and choke power supply. James output transformers. CCS…
