Chris,

when I got those large 7Hz-1kHz transformers I soldered one of them in my regular Melquiades and listed what it did. Besides all necessary bass benefits I decided to see how plate current would behave if I have no limitations for core saturations. My current gap is 200mA and while I moved with increment 15-20mA form 150mA to 250mA I could detect change in sound. Primary it has to do with discolorations and eating up the transient. The lower bass was changing but very insignificantly. However, when I connected the big trans then the tower become way more sensitive to even to 5mA. I would say that the drivers reacted like something damped them. I really do not know what is the reason. At the current Milq the power transformer is 350mA and the last cap 1000uF. I do not worry about it now and I am sure I will return to it when I will be doing the Super Melquiades

Also, I think I stressed too much (I was excessively surprised) the accent of my phrase “even within 5mA affected bass HUGELY”. I would correct it saying that the change current within 50mA affected bass HUGELY and the even change within 5mA affected bass auditably. In comprising with a “regular” 21Hz/200ma/9H transformer the semantic would be the following: change current within 50mA affected bass slightly auditably but the change within 5mA affected nothing.

Meanwhile this is the Zarathustra’s thread….. :-)
