Just a quick update, on opening her up I found C409 15uf/450 had leaked electrolyte, so have ordered three to replace the row of them.

Turning to the transistor replacement, can you believe that every si transistor in my stash is an NPN rather than the PNP called for here. I have ordered some BC 388's to try.

I cleaned the timebase and trigger controls with Servisol 10 but this made no difference.

I would like to check the power rails next but am unsure where to take my reading from.

Best
Dave
