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.
