This is a vintage 1965 Airline 62-9023A electric guitar amplifier. Nearly identical to the Supro 1624T “Dual Tone” model, this Valco-made combo amp features a single 12″ speaker, a duet of 6973 power tubes, and unparalleled tube tone. This particular example is in very excellent 100% all original condition and includes an entirely matching set of original RCA vacuum tubes and the original “Daisy” door stop footswitch. This super clean specimen is cosmetically well preserved, fit for a museum, a private collection, a special studio, or even a player’s private arsenal.

While it remains an unresolved discussion, many enthusiasts claim the 1624T was purportedly used by Jimmy Page on Led Zepplin I and IV. And whilst Page himself has admitted such, others argue that his 1624T was modified with a new baffle that accommodated 2×10″ speakers. Regardless of what Jimmy Page did or didn’t use, this amp is still regarded as one of the best vintage amps ever made. Period. It is reasonable to assume that Page would have an affinity for the 1624, because it sounds beyond incredible, and is partial to a recording environment. Similar to a tweed Deluxe but with a British edge, the 1624 is one of the coolest vintage amps with the most practical character.
The first version of the 1624T amp, whereby 6973 power tubes replaced the previous version utilizing 6V6 tubes, was introduced in 1958. The 2nd variety, the 1624TN introduced in 1960, was manufactured for a little over a year. That amp utilized: (1) 5Y3 rectifier tube, (2) 6973 power tubes, and (3) 12AX7 tubes through a 1 x 12″ Rola speaker. So, this amp best resembles that variant 1624, with an identical schematic and component configuration. The most significant difference is the use of a Jensen C12-R in the Airline equivalent, as opposed to the Rola installed in the Supros. The sonic difference between the 2 speakers is important, as the Jensen produces full-range smooth overdrive with clean headroom, while the Rola produces a more mid-ranged slightly saturated sound.
