Vintage Tube Amp

Up for sale, a 1969 Ampeg B-15N Portaflex tube amp in good working order, complete with the original trolley and full vintage tube set. The B-15N is one of the most recorded and highly regarded tube bass amp circuits of all time, and this classic four-input vintage model delivers the goods through the original 15 Eminence ceramic magnet speaker. Manufactured in the USA by Ampeg at their Linden, NJ factory and just given a clean bill of health from our techs here at Mike & Mike’s Guitar Bar, the amp is powered by a matched pair of properly biased Phillips 6L6GC power tubes. Notable for the addition of Ultra-Hi and Ultra-Lo rocker switches for each channel not found on earlier iterations, this B-15N has surprising output given its modest power and excels at a dynamic and detailed tone that can be extremely warm, or distinct and bright. Paired with a Precision Bass, it’s the perfect recipe for Motown thump. The original transformers are both present, and the preamp is virtually untouched, with original CTS pots that date to mid-1969. Along with the Phillips 6L6 power tubs, the amp features a trio of original Ampeg-branded octal preamp tubes and a vintage 5AR4 rectifier. A new three-prong power cable has been installed. The stock Eminence speaker has a clean frame and date code from the 24th week of 1969. The cabinet retains the original smooth black tolex, while the baffle has been professionally regrilled with black and silver cloth that closely matches vintage spec and is fitted with the original large metal Ampeg badge. The faceplate retains virtually all of the original blue pinstriping. Wear on the cabinet includes minor scuffs and edge wear, with wear through the tolex on the back two top corners and a couple isolated additional spots. As the photos show, this B-15N would look great in a studio. The original screw-on trolley is included.
