AMPEG B15N Portaflex Bass Amp

Let me introduce you to Vince - an excellent condition, very clean, absolutely phenomenal sounding AMPEG B15NF Portaflex Flip-Top Bass Amp.
“Vince” is a 1967 30 watt B15NF (serial # 052718) and is paired with a 1965 double-baffle Cab (Serial # 006013) with a factory optional 1963 build date ALTEC 421A 15” Speaker (391332). He has been recently restored and serviced: the electrolytic filter caps, and the electrolytic coupling caps have all been replaced with a FlipTops' cap kit. All other original components were tested and left in place to retain the original AMPEG tone. All the controls were cleaned and are noise-free. The octal plugs have all been cleaned and re-tensioned. A three-prong grounded power cable was installed for safety. All the tubes were tested , the 2 output tubes were replaced with new Apex matched Tung Sol 6L6GC “STR”s, the 3 original AMPEG 6SL7 preamp tubes are still very strong as is the 5AR4 Rectifier tube. The factory original 4-pin XLR speaker jack with protective standby switching is still in place. Vince has 2 channels - channel 1 has 2 inputs - one voiced for Guitar ( bright) and the other for Bass (normal), Channel 2 has one normal input. This amp also has the factory alternate ALTEC 421A 15” Speaker in excellent shape with no rubbing or scratching and sounds excellent. The cab gasket strip has been replaced as were the original amp shock-mounts - replaced with the non-fall-through versions from FlipTops. The top latches are also in excellent shape and strong. The original factory trolley is also included and also in excellent shape.

The blue diamond tolex has been thoroughly cleaned and has some very minor scrapes. (see the pictures) The chrome faceplate and chassis has been hand polished though some pitting and etching still remains. Vince has his own custom factory engraved light-up lucite logo that also serves as the pilot lamp. The handle has been replaced with an AMPEG blue leather handle. The original grill cloth has a few snags but is otherwise clean (again - see the pictures). Additional photos available on request.

This amp is extremely quiet at Idle but has that classic AMPEG bass sound that was made famous in all those STAX and Motown hits of the 60’s . This is a dynamic, versatile amp for any player, and it’s a classic time-machine. If you’re looking for a great original version of this vintage model, you’ve found it.
