By the way... df_genius talked precedently about a single 50 amps output device, a BUV20 which is unfortunately obsolete. Maybe another type will do? I like the ldea of having only a pair instead of four or more to avoid some pifalls and also increased capacitance load on the gain stage...

The stock version will do that? Half voltage? Down to 2 Ohms and give proportionnal current? At .01 ohms...from 10 to 40KHz? With all respect to this amp that I like very much...I don't think so and this is not a lack of irrespect I have towards it. Also all this is not necessarily an absolute...

Hello PigletsDad and thanks for reply "...meaningless - like marketing hype" Yes I know perfectly what you mean but I insist on the terms almost perfect as this does not represent a "fidelity fudge factor" but simply a desirable Zout and Zfrequency linearity for the unique reason of...

Hello PigletsDad Thanks for reply. It is great advice from you but I'm not at the testing point right now. Nothing concrete on my test bench! I'm planning for incoming future. I always try to get things the rightest way before starting something. Like life, designing should be smooth...

Hello df_genius OK...nice but I just checked...BUV20...obsolete. LL

Hello SJ Thanks for suggestion. Well, I didn't think about using multiple output devices to increase output current capabilities. It's a good idea and surely the most logic one! I now understand why I chose to use two amplifiers and parallel them together and I realize now it's a bad...

Hello My first post on PFM so hi everybody! Few years ago I bought 8 of NCC200 power amplifiers PC board kits and got great success with them. By the way I'm talking about the old, single-sided ones. Right now I have two left of these. And I have a project for them. I want to build myself an...
