Wow! That's what's great about A'gon, not just facts and information (which is what I was looking for) but interpretation of the information and advice about what's most important.
So along the way there was: A signature output transformer, Resistor changes, InfiniCaps, B+ Fuse change, Soft start modules, Super Balanced input circuit.
I talked to a dealer today about the newest versions to be released soon and he did mention the auto-bias circuit (which I can live without) along with the new cosmetics (that I happen to like).
I will drop Bea a line to see if she can put the upgrades together with a serial number.
Thanks Albert & Zaikesman for your informative posts, it's exactly the info I was looking for.
