Quad 303

Stereo Power Amp - Boxed

This iconic 1970’s British power has been tested for around 2 hours and is in full working order.

You might notice that this is fitted with a 5-Pin DIN input socket, rather than the regular Quad 4-Pin socket. We did consider replacing this but the 5-Pin DIN socket might be desirable for the new owner, so we have left it in place. However…. we have also included an original Quad 4-Pin DIN socket and wiring just in case the new owner wants to re-instate this.

The 5-Pin DIN socket is wired left & right to pins 1 & 5. We have also included a 5-Pin DIN to 4 x RCA cable, which will enable this 303 to be used with any other pre-amp with RCA output sockets. The L & R plugs to be used are the red and white. Yellow and black can be ignored.

Multi user switchable mains voltage so this will operate in any country.

This comes with correct Bulgin mains cable, along with the additional cables and socket shown in picture 12.

We do have a copy of the original user manual as a PDF on our computer, which we will be happy to email to the new owner on request.
