Re: D718 & B688 Transistors - Substitutes?
The Technics design looks good, worth restoring. New stuff is so cheap and sounds terrible, hard pressed to use five transistors per channel and overheats.
The FET phono preamp is nice, I would put in a better op-amp than NJM4559.
Polar vortex is usually on top of us, or the UK when the gritters come out. -33C last night, time to fire up the tube amplifier.
