She is still making beautiful sounds and amazingly enough...I am still using the same 6550's. I actually just got them back from being tested by Jim McShane and they still have over 85% life left in them. (He tested them at full operating voltages)
I think they have around 2.5-3k hours on them.
Any who, again a BIG thanks to Bob for building me a great amp!!
Lately, I have been using it more and more. I am watching Moonshiners on tv and using her for the sound....I think my Carver is getting jealous!!
Hey Bob, I like the looks of the 500w monoblock you are thinking about. 16 power tubes?? May need extra air conditioning...lol
