Since this thread was refreshed, I'll give an update... I've been gigging that Twin since March. I love it, it's a great amp. I also love the Pro, which is why I bought it back from the guy I traded with. They don't make em like they used to, and it always pays to have a backup. I had a few problems with the Twin, they basically amounted to a faulty screen resistor and some bad tubes. I swapped all the screen resistors and gave it a thorough cleaning out with canned air, contact cleaner, a soft bristle brush and some q tips. A new quad of 6L6's later, and It was like having a brand new amp! Seriously, love this thing. Been keeping my eye out for another D120, but I refuse to pay three hundred clams for a fucking speaker.
I'll find one for the right price, It'll come around. In fact, I'm almost dreading it, this thing is so freakin frackin heavy with just the one D120 and a stock Utah... That other JBL can take it's sweet time finding its way to me as far as I'm concerned.
Hope you all have a very kind and grateful day!!!
