In the Thread: Devid Berning amplifiers: the anti-trnsformers frenzy?
Post Subject: Transformers vs BerningPosted by drdna on: 9/24/2007
Well,
Berning is a genius to be sure. Here he fixed his sights on the "evil" output transformer. Every part of the circuit alters the sound somehow, of course, and the goal is to find the least damaging topology. The question is asked here: what will happen to the sound if we can match output impedence in a different way to OTL or output-transformer designs?
I am not an expert in circuit design. But my recollection is that the D-class analogy is an apt one. I like to think of toplogical change in terms of an organic visualization of the electricity.
traditional valve-OPT: A guitar where the vibration of the string transmits through the air to the guitar which responds with vibration, only the OPT is imprefect, so the guitar may be poorly made, or filled with jelly.
OPT: A team of thirty midget firemen with 30 miniature firehoses trying to put out a blazing building.
ZOTL: Taking block of wood, cutting into paper-thin slices, using Xerox machine to make magnified images and putting the giant copies all back together into a big stack.Rerurn to Romy the Cat's Site
