Default Re: Stella ST113U- distorted sound causes ?

Thanks everyone for the concern and very informative replies. Thankfully I'll be seeing a retired electronics engineer friend this weekend in London and he may be able to test all the valves for me. He might even have an output transformer.
Of course I will be testing everything else as advised above before sticking any new valves in.
