My friend is building speakers that can run on 1-watt. I was asking him what 300B amp (preferably mono) he would recommend. He came up with this and said it is easy to mod it to make it sound even better.
300B Tube Amps with 15/16 Watts Per Channel?
Felix Audio makes the dual 300B amp "Lybra"--are there any other manufacturers of that gear?.Does anyone have experience using two each 300B tube amps modified to be two monoblocks with 15/16 watts output power each? If yes, did you hear any difference in the exquisite 300B sound other than more power? All experiences and thoughts appreciated. (Yes, expense is already noted)

@vthokie83 Interesting. If you do get the chance then please post your impressions! |
@vthokie83 Just curious. What speakers is your friend driving with the Blackbird 300b amps? Just another data point! |
@yyzsantabarbara A nice move that most tube designers agree on is bypassing the cathode resistor. The tube can behave much better. I don't like the 6DJ8 and its variants; while they are quite linear, they are also very prone to microphonics. The schematic (if accurate) indicates it could really do with a grid resistor on the input stage. Since an EL84 is used, an ultralinear output transformer could also be used, resulting in lower distortion in the output section. I know a number of designers that don't like UL operation but as far as I can make out they are intentionally trying to make more distortion. |
