As I recall the key was adjustable and swing was about 40w.

Hello all I've got many Black Cat EQ's in R.I. what I do is see what the radio is keying and then turn the JB down to 1 watt less than the radio dead key I personaly Key 4 watts into my JB 12 and adjust it to 3 watts and with a good tube it should swing around 80 watts my jb 200A i key 4 into it and ajust the key to 3 and she swings around 200 hard this way theey are not over driving them and the tube life will be better
well that's my 2 cents for today BT634 John in R.I.
