Your Guarantees

DANGER - AC mains voltage and high DC voltages

RF power amplifiers using electron tubes (valves) contain high-voltage circuits which can be lethal. These boards are intended only for users who have sufficient competence and experience to work safely with high-voltage circuits, and are to be used at your own risk. We cannot accept responsibility for any damage or injury.

Product Guarantee

If you are dissatisfied with any of these products, you can simply return the complete product and I will refund the full purchase price. 

Support from the Designer

My policy is to help you get your board working, and then help you to keep it working. I set no time limit to this support.

The support follows the hardware, so if you sell an amplifier containing one of my boards, please remind the new owner that the product still has my support.
