Your drawings do appear correct (and thank you again) and I shall add in the missing values to the relevant components and upload the amended schematics.
I have tested the valves and they do appear to be in tolerance.
The EF86 is working as the tremolo section will only work when switched on, the oscillation can be heard with the volume is turned right up .
Now it has more volume (I'm still not convinced it 100% yet), I'm thinking it is going to sound bright even with a 1000pF coupling cap. Perhaps I am expecting a lot from the Richard Allan speaker?
I have learnt so much out of this little project so far and it definitely nearing completion now.
Best Regards
