Printed Circuit Boards.
I am glad to report that PCBs for my various preamp and power amp designs are once more commercially available. The Signal Transfer Company is the same organisation that produced the PCBs when they were sold through Electronics World. The PCBs are made to the same artworks as before, and so should work just as well as the originals.
You can find them at:
Please bear in mind that I have no direct connection with this company. If you have any queries about their products or services please contact them directly. Likewise, if you have technical difficulties please don't expect me to be able to sort them out by email.
