I'm looking at this 1963 Blonde Fender Bandmaster head with Blackface Vertical Dual Showman cabinet. Wondering what's a decent price on the combo. The Bandmaster is kind of beat cosmetically, missing back cover(see pics), and not sure about some of the numbers: Output Transformer: 606-3-05 / 12571xA(hard to make out)? Power Transformer: 606-3-40 / 125C1A Choke Transformer: 606-6-14 / 022848 Not sure why the choke transformer reads from 66. Bottom of the chassis reads: AB4563(inked)? Right side of chassis reads: A00992(stamped) Cabinet is humongous, measuring: 40H x 30W x 11D Sealed back with a million screws! Speakers appear to be 15's. Old tubes in there; the amp probably needs to be completely gone over. What price is safe on this combo, or should I pursue only the head, and at what price?
