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 loaded d3a for linear operation.
- Audio Note copper PIO coupling caps.
