Hi Tom, Thank you for your kind comments. Since bias is adjusted with the amp at idle, whether or not a load is attached does not matter. That is a great example of a case in which the rules can help. Doing a quick bias tweak on the bench need not involve attaching the loads.

Hello Steve, Very interesting information! I have fallen into the category of one who lives by dummy loads! So, having made the investment in several sets, I'll probably just keep using them. But, I'll take some solace in knowing that should I ever fail to remember (and old age can do that to ya), or if I ever find a broken switch (ha ha), I'll at least recall your comments and not have too huge a panic attack. I am curious about one thing; does the 'lack of load' have any affect on bias draw, such that either 'with' or 'without' might affect proper adjustment when in actual use? Many thanks for the articles and website! Great Stuff! Tom D.

Hi David, Thanks for the kind words! Will give the transformer questions some thought...

Nice write up! These are great rules from the perspective of safety for the output tubes. As a suggestion, it would be nice to also include any relevant rules from the perspective of safety for the transformer as well!
