Hi everyone.... First post here so please be gentle.

I'm in the middle of buying all the various components for a DR103 build. Most of the parts are coming from Modulus Amplification. Obviously the original DR103's didn't have a variable bias adjustment, but I've read that in clone builds and with modern valves it's good practice to wire in a variable resistor to enable bias adjustment.

Opinions please.... I've checked the Hiwatt.org website and they recommend a simple adjustment circuit
