Tube chart is NE, May of '64 Power tranny is 9th week of '64, Output tranny 13th week of '64, choke 15th week of '64. Original matching Utah speakers date 19th week of '64. The power tubes are period correct GE's but a couple preamps (originals included) have been freshened up with new JJ's. Also, needed fresh filter caps. All done and ready to rock. The Fender Concert amp was a 2-channel, 4 by 10-inch combo with onboard vibrato. This amp's circuitry is very similar to that of the Vibrasonic but features a different tube complement. In its first year, the tolex used on the Concert amp changed somewhat: originally the brown had a pinkish tint, before switching to a darker shade of brown by 1961. After 1963, this amp used Fender's Blackface cabinet style. Anybody who knows these amps know have that they still have that coveted brown tolex Marshall type tone out of a Fender amp. This is no exception and sounds incredible.
