Might be a Sinclair exaggeration, maybe 50mA with brightness at zero, volume at zero, and tuned to a strong signal so that AGC action biases the transistors right back.

The circuit description indicates it is entirely discrete, no IC's (well, it is 1966) whereas what went into production in the 1970's used three custom IC's.

All the same, it was an achievement!
