1624T DUAL-TONE The “Dual-Tone” 1×12 combo amplifier is the undeniable rock star of the mid 60’s Supro amplifier lineup. Vintage 1624T amps have been sought-after for decades because they embody the most desirable aspects of the Supro sound. As the Dual-Tone’s volume knob is turned beyond noon, a fat and compressed clean tone evolves into an immediately recognizable grind that remains articulate and listenable even when turned up to full blast.
This 24-Watt, 1×12 tube combo can easily be driven to glorious saturation at a manageable gigging volume while retaining exceptional clarity and bandwidth, at any level of gain. This amp’s unique mojo is largely defined by the use of 6973 power tubes in the amplifier’s output stage. These robust 9-pin tubes were employed extensively in the mid- and low-power Supro amps made 50 years ago. 6973 tubes look like EL84s but they deliver a distinctly American voice that has been missing from the world of tube amplifiers for far too long.
