The Black Flag 50w amps were originally made in 1966 to 1967 and are as rare as hens teeth, They were a transition from between the JTM45 and the JMP models which followed later. The amps now featured EL34 power valves and moved away from valve rectifiers, they still had the shared cathode resistor on V1, lower power supply filtering and the same tone stack as used in the JTM45, which has slightly less mids than a later JMP model, allowing for great clean sounds as well as great crunch tones when pushing the EL34's

The kit comes in a steel chassis that allows you to fit a valve rectifier if you want the saggier earlier black flag experience or you can stick with the solid state rectifier for a faster response. There is also an additional turret on the board if you want to split the V1 cathodes.

We have tried to make the options above flexible enough to build the exact amp you want, but if you want some small differences please let us know, Our recommendation are as follows

  • High Spec: Sozo Coupling Caps, F&T Filters,Carbon film Resistors
  • Good Spec: Mallory Coupling Caps, Modulus Filter caps, Carbon film Resistors
  • Budget Spec: Yellow Modulus Coupling caps, Modulus Filter Caps, Carbon film Resistors

If you select to include valves we typically supply JJ Electronic valves with this kit

You can also select your faceplate colour and knobs, we make faceplate's to order so if you have any special requirements let us know and we will see what we can do to help.

Our transformers are high quality units based directly off real Drake transformers that we pulled apart to measure every detail, They meet modern safety and insulation requirements. The power transformer is supplied for the wall voltage in your country only. If you need a multi tapped power transformer please contact us at time of order.

Cabinets are made to order and we will ship the complete kit with the cabinet. It is cheaper to buy the cabinet with the kit compared to purchasing it later.
