6N7 tube preamp (Heavy Metal)

Construction is in a timber box. There are three switchable RCA inputs and power is supplied by an external 18V 2.2A AC power pack. Internally 255V is developed with a linear PS and regulated 12VDC for the heaters which are wired in series.

An Alps blue velvet potentiometer is fitted at the output for attenuation control with a fine solid brass knob to compliment the gold right-angle RCA jacks, name plate and ventilation holes. Wire wrap wire is used in the signal path. The power supply and amplifier are on separate circuit boards. Bitumanised heavy aluminum foil is used to line sections of the timber box for resonance control.

For more info, see the 6N7 metal tube preamp thread on the discussion forum.
