Quad 306 power amplifier and Quad 34 Control Unit. excellent condition. No scratches or marks. Includes the stand so control unit appears floating. This also doubles as a cable tidy hiding connecting cables. It has had one speaker connector ( female bayonet ) replaced due to outer plastic ring breaking. Unit Works really nicely. I use these with my Celestion 551s ( also for sale ) Power connecting cables are included & original instruction books. I’ve had this system from new. I don’t wish to post the item due to its delicate nature ( don’t trust couriers )
