I just picked up a 1961 Bandmaster head & cabinet. The head is at the shop for a checkup. I have some cabinet questions. 1. Someone replaced the 1x12 baffle with a 2x12 baffle. I have period correct Jensens in there but I was thinking about going back to 1x12. I saw one of these on CL with a JBL D131f. That would've been 16 ohms. Does the Bandmaster want a 16 ohm load or 8 ohms? 2. What speaker(s) would've come in the 1x12 cab? Is the JBL 131 original? 3. They also pulled the wood strips off the inside back panel, left the nails but tore off the insulation. I blame drugs because they must've dropped large quantities of LSD and decided to paint the tolex black. I dunno, maybe they dreamed they saw a red door and wanted to paint it black...fortunately they passed out before they ruined any more than the back. I can get the point off with lacquer thinner but they also replaced the screws with friggin drywall screws. Would the original screws have come with those cup shaped washers or just screws alone? Any information will be greatly appreciated! THANKS!
