Mystery Valve
Thanks to Tim (g4wim_tim) I have a selection of unknown valves the majority of which I have now identified (thanks to them all being Mullards with etchings!)
There are a couple that have got me puzzled however so I thought I'd show the experts!
Valve 1 there are 3 photos attached. The remains of a Mullard label are visible with the word Holland
There appears to be a code on the bottom reads Yk (I think) and L2D. I cant find the code Yk in the Phillips list of codes and I don't have another valve like it anywhere.
Valve 2 is just the one photo. The code on it identifies it as an EF86en. Is it really an EF86 with a top cap?
Any ideas about these?
Regards,
David
