Default Re: Mullard 3 watt amp - gobsmacked !

Hi,

Yes, they are a rather nice amplifier. I’ve a pair of the Sterns Kit Mullard 3-3 amplifiers with the Parmeko output transformers.

One thing I observed is the EF86 has to be good to get the circuit working at it’s best.

The DC coupling from cathode of the EL84 to the screen grid of the EF86 & anode of the EF86 to the grid of the EL84 is very intresting, along with using the EF86 in starvation mode.

Terry.
