many thanks Andrew .I can already see that there are discrepenceys .the bigest problem i have is the mods done to the output valve (now el84) the cathode bypass cap is disconected ,infact the lead won't reach the valve holder.mind you this cap is leaky so will need changing.i think i will try and sketch out the circuit as it is and see where i go from there.
it was not unusual to change output valves eg cbl31 for an el84 + a couple of diodes .but an el 41 was/is not rare so i dont understand why it was done in this case?

if its made by hand it can be repaired by hand
