Ampeg B-15N Portaflex, * LOCAL PICKUP ONLY Model Tube Bass Amplifier (1964), made in Linden NJ, serial # 409090, blue checked Tolex finish.
Overall this is a very nicely preserved example of the all-time classic recording bass amp, Ampeg's B-15N. From its inception until today, this model has been the preferred in-house bass amplifier for the great majority of professional studios, and was a lower volume gig standard as well. The serial number 409090 on the label inside the cabinet indicates the amp was made in September of 1964. We see a decent number of period B-15s, but most have seen decades of use and often show heavier wear and/or modifications. This 1964 model is one of the cleaner we've had in our showroom and appears to have been very well cared for and is also a wonderful sounding amp.
Height is 29 in. (73.7 cm.), 21 in. (53.3 cm.) width, and 13 3/4 in. (34.9 cm.) deep.
Externally, the amp is very well-preserved. The signature "Blue Check" Tolex is in nearly pristine shape, with only minor wear. The metal corners and hardware show moderate signs of corrosion There is some very light scuffing to the tops of the transformers and tube cage from decades of the amp being flipped and stowed in the cabinet. The original Ampeg logo from the upper front of the cabinet is present and the handle is a correct modern repro; this part is usually replaced by now. The amp comes complete with the original dolly as well.
Internally, this amp remains nicely original. The speaker is a (likely later) CTS-made 15" unit, not unlike the speaker that came stock in many of these amps. It has been professionally reconed and sounds fantastic. The amp has seen our typical servicing and maintenance, including replacement of all electrolytic capacitors, adding a grounded 3-prong power cord, cleaning of all sockets, pots and jacks and biased to spec.
Overall this amp is in great shape and sounds truly fabulous. The speaker packs a nice even punch, with no boominess or rattles, even at higher volumes. This is a lovely example overall; a true classic amp and perennial studio staple. Overall Excellent - Condition.
