|Ultra-LD Mk.4 Amplifier prototype PCB [01107151 RevB]|
Prototype PCB for the Ultra-LD Mk.4 200W Power Amplifier.
This board has been discounted although it's almost identical to the final PCB. You MUST cut the track completely from D6 which runs to the far end of the adjacent 100kΩ resistor. Once the components have been fitted, add a tiny length of wire to join the disconnected pad of D6 to the nearest pad of the adjacent 100kΩ resistor.
Double-sided PCB with plated through holes, solder mask and silkscreen overlay.
135 x 93mm.
