| 300b lovers Hi @lynn_olson @atmasphere , Thank you a lot for detailed answers! I have another question: In balanced push-pull self bias output tubes is not a big issue because the cathode resistor and capacitor are out of the main signal path. But what... | |
| 300b lovers I ask again this technical question again. Which rectifier is better: full wave or bridge? My driver stage power transformer has three taps: 250 0 250 and supports both - full wave and bridge. Full wave affords use x2 times bigger DC current. Why... | |

| 300b lovers In my case, I compared the sound of my amplifier with different IT resistor load. 120K (Kiwame 2W) vs 56K (Alan Bradley 2W). The sound with 120K resistor was too bright and rough, with 56K tonal balance was more natural and sound was more refined.... | |
| 300b lovers Hi @donsachs and @lynn_olson , Here is square wave 1KHz on my amp output: https://photos.app.goo.gl/jcdjn88Q71WaEvoR9 Output transformer and driver IT have much wider bandwidth compared to input to driver IT. During the measurement the 6sn7 cur... | |
| 300b lovers Hi @donsachs , I changed a load resistor 56K Ohm (Alan Bradley 2W), in my SET amplifier. And still have a 2-3 times bigger overshoot vs Blackbird has. However the sound is more balanced compared to the 120K (Kiwame 2W) load resistor I had befor... | |
| 300b lovers All classic vintage PP amps from 50-60 have very weak PS in terms of chokes, power transformers and especially capacitors values. If you use the same power supply for SET with no feedback with a such PS will be a disaster. But many of these classi... | |
