Hi All,
Of the several burns I received from power output tubes, the latest perpetrator was a KT90 in my PPP amps that I am rebuilding with a new driver. I was tweaking the bias pots and phase compensation when the side of my wrist bumped into the hot tube. There was no pain, but the burn started to blister today. It still does not hurt but is unsightly.
I feel electric shocks and burns are just part of the business. If you have any cats, make sure you build your amps with cages over the hot tubes. The dog may bump his tail into an exposed driver board, so a cage should go over that too.
What are your all's experiences with this stuff?
