Trace Elliott big boy’s amplifier

Local musician brought this amplifier in. Not a lot wrong, but some puzzling things. Open circuit fuse holder? Couple of resistors way out of spec. Strange as the parts used are good quality ones. The KT88 output valves looked original and probably done many hours work. So, thinking the valve tested would show them as tired, wrong! All good. Great output and sounded very nice. Good to see a manufacturer popping in a fan to get rid of the residual heat.
