I'm selling my Yorkville Bloc250B head. I would like to get $150 US or $200 Canadian for it + shipping. Features/Controls: Two channels with separate gain controls Sustain (it's a basic compressor, I think) Presence On/Off (high-mid boost) Parametric EQ (freq, Q, cut/boost) Master Volume 4-band EQ Effects loop Line out Balanced DI out 175W into 8 ohms, 250W into 4 ohms Versatile, loud, punchy, heavy, sturdy... It was made in the late 80's right when Traynor changed their name to Yorkville Sound. The original transormer started buzzing at some point so I replaced it with a super-high quality toroidal transformer. I'll post some pics tomorrow.
