Up for sale, a 1963 Ampeg B-15N Portaflex fliptop amp combo in excellent condition, freshly serviced and loaded with a JBL D140F speaker. The B-15N is one of the most recorded and highly regarded tube bass amp circuits of all time, and this early (third year) example has just been given a clean bill of health from our techs here at Mike and Mike’s Guitar Bar. As the amp that defined the Motown bass sound and a must-have for studios worldwide, the B-15N is the undisputed king of vintage studio bass tone, with a thumpy sound that is round, detailed, and versatile, bringing out the best in your instrument’s natural tonal characteristics. The two channels each have a unique voice, with Channel One being a bit more mellow and smooth, while Channel Two has a touch more grit and bite, also making it an excellent choice for guitar (diming this channel out delivers a particularly nice overdriven roar with a humbucker or P-90 equipped instrument). The circuit retains the original transformer pair, with a fully recapped power supply and a couple new Sprague caps in the preamp. All but one of the original CTS pots are present, with visible date codes from the 6th week of’63. The original plexiglass Ampeg badge is present, illuminating as it should when the amp powers on. The head and cab still connect via the original multi-pin connector, and the amp has been upgraded with a three-prong power cable. The tube complement includes a matched pair of Tung Sol 5881 power tubes, a vintage Westinghouse rectifier, and the original trio of Ampeg by Sylvania 6SL7 preamp tubes. The speaker is a vintage JBL D140F 15 alnico magnet driver. While Ampeg would include a CTS speaker with the B-15N from the factory (or in some cases an Altec for an upcharge), this JBL is arguably a better option, offering the ideal blend of dynamism, headroom and overall efficiency for a tube-driven bass signal. The original tube chart is intact inside the cab, with the stamped serial number dating to 1963. This is a well-kept example, with bright chrome plating on the chassis, white silkscreen text, and all of the original knobs present. The original latches are present and the plastic handle for the head tray is MIA. The original blue diamond covering is notably clean throughout, while the trolley is a modern replacement.

Marshall Lead 12 Watt Combo Guitar Amplifier for parts or repair. The pots were scratchy and tried to pull off the knobs to clean them and one of the shafts from the pot came off. I never did clean the scratchy pots. The Marshall Lead 12 is a highly regarded 12 watt solid state amplifier produced between 1984 and 1991 as part of the JCM800 series. Despite its compact size and transistor-based design, it is famous for capturing the “Marshall growl” and iconic British overdrive usually associated with larger tube amps.

For sale is a matching vintage Lafayette tube audio pair consisting of an LT-80A FM tuner and LA-55 mono integrated amplifier. Both units have been fully restored, serviced, and tested. They are operating properly and sound excellent. The LT-80A has strong FM sensitivity and receives weaker stations well, even with a very basic antenna. The AFC functions correctly and keeps stations locked in once the tuner has warmed up. As is typical with vintage tube FM equipment, there may be a small amount of warm-up drift with AFC switched off. The LA-55 amplifier plays clearly and strongly with no significant hum or operational issues. Controls, switches, and functions have been checked. Cosmetically, both pieces are in nice overall condition for their age. They present well as a matching set, though they are not museum-perfect and show some normal age-related wear. Please review the photos carefully for exact cosmetic condition. This is a great opportunity to own a restored matching Lafayette tube tuner and amplifier set that is ready to use, rather than an untested project.
