SRPP Headphone Amplifier

Here we propose the use of two EL84 (6BQ5) power pentodes in triode SRPP configuration, without an output transformer The reasons for using the EL84 (6CA5) are mainly that it's cheap, widely available and forgiving of the odd overload condition. Here, two of these valves are SRPP'd into an amplifier that's sure to reproduce that warm thermionic sound so much in demand these days.
