This means more mids in the 0.022uF AB763 since less signal leaks to ground through that cap and the 6,8KOhm resistor.Our recommendation in a sparkling 4×10 Super Reverb is the lower cap value that allows more beefy tones.If you seek a scooped tone with less mids,go with the higher cap value.Bund Wall - an overview ScienceDirect TopicsThe general rule is that the secondary containment should have a volume equal or greater to 110% of the volume of the largest tank being protected.If multiple tanks are enclosed,then only a spill from one tank needs be considered.Although a system such as that shown in Figure 11.1 is inherently safe,the drain valve in the wall has to be checked.It is needed because it will be necessary to drain rainwaterBunding Oil Filled Transformers To Bund or Not to Bund Apr 25,2019·Usually sealed distribution transformers up to 630-800 kVA dont need to be bunded.Neil Denbow (Director at Eden Transformer Oil).Manuel,BS EN 61936-1:2010 doesnt differentiate between breathing and hermetically sealed transformers,it is defined by the volume of oil in the transformer.
