The Phonostage uses the “Eros” circuit designed by Paul Joppa of Bottlehead; with one stage added for slightly more gain and lower output impedance. The signal side is an EF86 directly coupled to a 6922. The 6922 is cap coupled with a TFTF V-cap to a 6C4 transformer coupled voltage amplifier, which is coupled via another TFTF Vcap to the 125 ohm center tap of the Magnequest Nickel B7. This arrangement is ideal to drive the low- impedance TVC's in the linestage. The dual hybrid shunt-regulated power supply in the left box uses 6X5 rectifiers and 6S4 tubes as regulators.
