WebbHF is a means for designing safe and effective work systems, not a goal or outcome in itself. HF applies to all aspects of an organisation. The tool should not be prescriptive, allowing for different approaches to applying HF in different contexts. Scoring should be a range from ‘nil’ to ‘ideal’ on a simple 0–4 scale. WebbThis compact little amplifier is the brain-child of Pat Murdoch, ZL1AXB, in Auckland, New Zealand. It is only 11″ wide, 4″ high, and 9″ deep. In most respects it is a typical grounded grid linear amplifier, with the exception of a rather unique tuned cathode input circuit that was developed by Pat over 10 years ago. how many eggs per day should you eat
