- Page 3 Stand By Power amp Stand By switch: Use this switch to silence (0 position) the amp when you take a longer break. The amp‘s tubes stay nice and toasty, and the amp is ready to roll immediately when you ramp it back up to full power.

- Page 9 This packaging can be used several times - do not throw it away! Tubes When replacing the power amp tubes, the operating point (BIAS) must be set. If you use ENGL tubes with the same “grade”, the operating point does not have to be set.
