Is there anyone here who could kindly test a pair National ST shape 45s for me? I think one is faulty, but unsure which!

Happy to pay for return postage obviously!

Yeah, PM if interested. If its just a filament issue a simple multimeter will suffice which could avoid postal risks, if its emissions or c/h issues or something more then a tester is the best way forward.

Thanks. Do you have a tester if that's required??
