Karel-Mars Hi I had a chance to look closely at another beauty. Blondes came out just before Black Face amps and had slightly earlier circuit configuration. Here is a rare example of the craft:
Karel-Mars I actually do not know. Maybe someone know what speaker this is? There is actually some bad vibration (the type the Beach Boys weren't singing about ?) coming from the speaker. I need to remove the speaker to work out what is going on.
AlanRatcliffe Yes, it's an Oxford 12L6N - the L means it is a 30W speaker. A decent speaker until they made some changes in '66 - so this will be one of the better ones, although a Jensen or decent modern speaker will still be an upgrade. Exactly the same amp Mark Knopfler used on Sultans of Swing, BTW
FenderBender Awesome stuff Karel! I'll bet that Amperex GZ34 is still the original. Good luck with the speaker. I hope it's only cab lint in there ? EDIT: Strange mark on the one 6L6... Has the tube cooked or is that just a weird place for getter flash?
Karel-Mars Thanks Greame The tubes seems to be more or less OK. It is the getter that you see on the side. It seems to be common with RCA 6L6GC's.
