| 300b lovers Hi @donsachs @lynn_olson , I have 300B SET with 6f6 driver in triode mode. I did 2nd harmonic distortion calculation using 3 point method and 6f6 plate characteristic graph. So with RC coupling that I have right now I get more than 2% dist... | |
| 300b lovers I have a question to @lynn_olson I have 300B SET 6sn7 input, 6f6g in triod driver with RC coupling. One friend of mine who reads DIY forums and tries all this thing by himself, recommended me to enlarge cathode capacitors up to 100,000uF in input... | |
| 300b lovers Hi @charles1dad , I don't have practical experience. But theoretically 300B is winn-winn vs 845. 1. Output transformer has wider bandwidth. 2. Easy to drive. Driver tube and driver transformer. 3. Easy to build a high quality PS for 400v vs 10... | |
| 300b lovers The output transformer for 845 SET should be at least 10K Ohm. And it can't be as wide a bandwidth as a 3K output transformer for 300B. Another issue is that driving 845 tubes is much more difficult. A well designed 845 SET will always be inferio... | |
| 300b lovers Hi @lynn_olson , Thank you for very interesting information. Do you have any data high order distortion in 6F6 and 6V6 in a thiode mode? A friend of mine use 6BX7 double triode for driving. Is there any information about 6BX7? I heard 2 SET ... | |

| 300b lovers I heard that Sakuma used 300b driver tube for 300b. He always used transformer for coupling. To get 27 watts from the 300b push-pull it should be class AB. | |
| 300b lovers I have had a DIY 300B integrated stereo amplifier since 2006 built by one guy. But in all this long period of time I did dozents upgrade myself. The amplifier has 6sn7 input, 6f6 (in triode mode) driver and 300B. Cathode bias and C coupling betw... | |
| Modifying Crossovers I used my Altec 604e with the original N-1500 crossover. After 10 years I bought an autotransformer DIY crossover from Germany. I liked it more than the original one. As I understand lately the schematics of this new crossover wasn’t good but bet... |
