I am selling a rare DLS A4 4-channel amplifier in excellent condition. I sent it to Gordon the Amp Doctor in 2014 for a service and upgrade (this involved fitting high end preamp chips and optimising the output stage biasing), and until a couple of months ago it has been in dry storage.
The amplifier is in excellent working order, and excellent condition.
