Tuesday, March 7th, 2023Vintage 1953 RCA 6AQ5 12AX7 6X4 Tube Amplifier for Guitar Amp Rebuild MI-15910
Wednesday, December 28th, 2022





Up for sale here is this neat vintage tube amplifier. This came from an RCA MI-15910 tube reel-to-reel player from 1953. The power transformer is included, but was previously mounted separately, and it attaches to the amp with an octal plug. This has two potentiometers, a neon light, two 1/4 jacks, and a socket in the side for an AC cord (not included). It normally uses a 6X4 rectifier, a 12AX7, a 6AQ5 output tube, and a 5879 tube, but only the 5879 tube is included. That one has a metal cover over it, and I’m not sure if the cover is original. This is a neat little tube amp and you could build an amazing guitar amp with it. This is in good physical condition with light to moderate overall wear. It measures about 12.75″ long, 4″ deep, and 2.25 tall. The last picture shows the tube layout, but the paper tube layout is not included, sorry. It will be an amazing guitar amp once it’s done. I will guarantee the transformers to be good. Look at those neat vintage caps! Please see my pictures for details. If you have any questions, please ask. I have more amplifiers and other vintage electronics listed–feel free to take a look!

1970 Fender Musicmaster Bass Vintage Tube Amp 1×12 Silverface, 6AQ5 RCA Tubes
Monday, July 20th, 2020


Up for sale, a 1970 Fender Musicmaster Bass 1×12 tube amplifier in excellent, 100% original condition and in perfect working order, featuring the original matching RCA tube set. While designed as a companion for the Fender bass of the same name, this Class A/B 6AQ5-powered tube amp has found favor with guitarists for its low wattage and sweet, dynamic tone. The open back cab and single 12 ceramic speaker produce a range of sounds from clean Fender sparkle to rich overdrive with the twist of a knob. Particularly valued for their usefulness in the studio, the Musicmaster Bass is one of the most popular and enduring circuits from the Silverface era. The circuit has just been gone through by our techs here at Mike & Mike’s Guitar Bar, and everything is working as it should, with the original RCA-branded 6AQ5 power tubes. Both the output and power transformers have 1970 date codes. The 12 CTS speaker has a very clean frame, original cone, and original round Fender label, with a date stamp on the edge of the frame from the 16th week of 1970. Cosmetically, the amp is quite clean and completely original, with stock smooth black tolex and silver sparkle grillcloth with turquoise stripe. On the polished aluminum faceplate, all of the blue lettering is present, and the original raised “Fender” logo is intact on the grill. All of the original hardware is present, including the rare Starcaster-style knobs only seen on the first iteration of this amp. Sure, there are a few small scuffs on the tolex and faint wear on the grill, but overall this is a very clean amp that would look great on stage or in the studio. Check out our shop “Mike & Mike’s Guitar Bar, ” and please let us know if we can answer any questions! We use double thick boxes, 1″ foam, and industrial 1/2″ bubble wrap to ensure that your amp arrives safely.
