I built this amplifier in the late 1960's for use in pubs, clubs and parties during my student days. As far as I rememer it was still in working order when it was put up in the loft around 40 years ago. It looks complete apart from 2 valves missing which I may have removed to mend something. The missing valves would be one EF86 and maybe a ECC83. The circuit diagrams are with it so should not be too much trouble to get it going again. Some of it is a bit crude as I lacked a decent tool kit and was just embarking on the construction of such things. The two transformers, output valves and quite a few components where bought new, other smaller bits, used what ever I had to hand. The size is 17" x 7" x 8" high. It does not comply with modern safety standards so I have cut off the 2 core mains cable. It will require a new 3 core mains cable and checked over by a competent person before being put into use.
