Thank you for your interesting GS35B amplifier project I am also considering constructing, as my 100W & 40M Delta Loop only gets around Australia, not DX!
A friend, Laurie VK3SJ built a very similar amplifier, ( have a look at it on QRZ) using GI7BT tubes in parallel so that is why I am comparing construction techniques.
