"The ECL86 was not introduced until 1962 and if looks as if the amp pre-dates this" Maybe, but all the valves have yellow print, which AFAIK were issued for the Mullard Golden Jubilee in 1970, so maybe all the valves were replaced in one go if the amp was made earlier. Thought i saw a C on the valve near the OPT, could be mistaken and it would make more sense if a EL84.
