1961 Tweed Airline GVC-9010A Supro 1688TN high power Dual Tone + Thunderbolt

Super rare and excellent condition 1961 Airline GVC-9010A amp - same circuit as the early Supro 1688TN with two 7027A (6L6GC) power tubes in the power section, a 5U4GB rectifier, and four 12AX7's in the preamp. My favorite Valco amp, and I've owned or worked on just about every one made dating to 1958. Cleanest of this model I've ever seen. Surprisingly versatile, one channel is essentially a Thunderbolt and the second has the voicing of a Supro 1624T Dual Tone - although with 30-35 watts class A output vs. 15. Plenty of power and volume for gigging as well as recording. Super lush tremolo. Channels are interactive and can also be jumpered for different voicing and presence.  Any 6L6GC or GB or 5881 is a direct drop in replacement for the 7027. Amp can also run a pair of 6V6's with a 5Y3 rectifier and, with a minor mod, EL34's or 6CA7's and a 5AR4 in the output section (EL34's sound awesome in this amp). One of the origial 7027's is microphonic, so amp will ship with buyer's choice of strong RCA black plate 6L6GC's (branded for Tung Sol), NOS Tung Sol 5881's, or a new pair of JJ 7027's. Cabinet has original pair of teal 12" Jensen P12P alnico speakers which sound amazing. Tolex and grill are excellent, no rips or wear through. Chrome has very minor pitting, printing is crisp. Original tremolo foot switch included. Amp is all original except for the 3 prong cord and previously mentioned power tubes. "Death cap" disabled. Comes with original schematic, owners guide, and bill of sale dated March 1962. The electrolytic caps tested great on an ESR meter and amp runs cool and quiet for its age. Cleaned and checked, deoxed pots. Amp sounds fantastic and you may never see another this nice.
