Re: Linear Conchord/RSC A11 30 watt amp
Hi Bill,
The early Vortexion 50 Watt amplifier used 807 valves. I’ve attached the circuit if it helps. Sadly there are no voltages marked on the diagram.
I’ve seen a fixed bias circuit for a 75 Watt 807 amplifier in one of the Brimar Valve and Teletube manuals. Maybe if you think it's of interest I’ll see if can find it and scan it for you?
Terry.
