Farnell Power Supply Unit E30/1 Refurb - #099

Farnell Power Supply Unit E30/1 Refurb - #099 Obtained from EBay for £15, this 1970’s PSU was made in Yorkshire! I have been unable to find a circuit diagram for my model, sold on EBay as ‘Farnell E30/1 Benchtop Stabilised Power Supply’ The only circuit I can find (E30/2) has two 2N3055’s as the main power regulation transistors, where as my unit only contains one.
