I stumbled upon (and subsequently bought) an Ampeg V4B today; the version with two inputs, a 6K11, and the metal switches on front. One of the 7027s was cracked, but the amp still functions, albeit obviously not up to it's full potential. Cosmetically, the amp is dusty and cobwebby, but probably a 7/10. So, I wanted to install a grounded power cord, check the condition of the caps (the tubes were all original Magnavoxes, so I strongly doubt that a tech has EVER been inside this amp). BUT -- I'm stalled at the starting gate! I can't get the PT side of the chassis out of the case...something is stuck and I don't want to apply excessive force. It seems like it just needs to lift up a bit to clear the front grille, but I can't get that side of the amp to budge. Is there a trick, some common problem that I'm running into, or do I just need to eat my Wheaties and muscle up on this thing?
