Battery Bias, did it - Photos

Posted by Branwell (A) on March 23, 2002 at 17:48:42

Hello,

I did the battery cathode bias to a Space Tech QA-112 this afternoon.

Not sure whether I like it or not. The pre sounds much faster, has more resolution across the board, the soundstage is incredible, the illusion of the instruments is soooo real, but it’s lost a little Tubyness which I like.

I’ll give it a few days and see.

Thanks for all the advise.

Here are some photos if interested.
