The Supro Blues King 12 amplifier uses 1 x ECC83 (also called 12AX7) preamp valve and 1 x 6L6GC power valve/power tube.
Over time your valves will lose their tone and their power. A brand new set of valves will get your amp sounding better than ever.
We always recommend JJ valves for this amplifier. This is because they guarantee you get awesome tone and long life and they don’t cost a fortune. Remember, JJ is one of only five manufacturers of valves in the world. So don’t pay higher prices for valves from the same factory that have simply been rebranded by other companies.
So restore the tone, the power and the sparkle to your guitar amplifier. Treat yourself to a brand new set of valves today.

What Supro say about this amplifier.
Front-end gain in the Blues King is supplied by a 12AX7 tube preamp and a FET-driven, fat boost function. In addition, the amp’s high-gain mode uses a series of cascaded FETs to achieve face-melting levels of distortion and sustain. 3-band EQ and Master Volume controls join the foot-switchable boost and gain functions to provide multiple layers of stackable overdrive for gigging, recording and home practice.
The 1812R Blues King features a custom-made genuine analog spring reverb, plus an effects loop for pedals and a line output for recording or feeding to another amplifier.
The vintage-inspired poplar wood cabinetry is based on the mid-50’s Comet model and comes loaded with a BK12 speaker. This custom-made, 12” driver was specifically designed to capture the magic of the original field-coil speakers used in American tube amps at the dawn of the electric era.
