| 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... | |

| 300b lovers Hi @atmasphere , How does excessive transformer ringing can influence on sound? Does it make it too sharp or bright? | |
| 300b lovers Hi @donsachs , Yes Dave Geren at Cinemag do great job! I use Hashimoto A-305 IT between 6f6 (driver) and 300B. The square wave was almost perfect at 10KHz, 20KHz, 30KHz. I use an 80K Ohm grid resistor on 300B. But I’m not sure this resistor is n... | |
| 300b lovers I have a technical question for tube gurus @lynn_olson @donsachs @atmasphere I put the intrastage transformer Hashimoto A-107 between the 6sn7 input and 6f6 driver tubes in my SET amplifier. The load resistor connected to the 6f6 grid was 520KOh... |
