| Is soundstage DEPTH a myth? Many Classical records made in real hall acoustic environment with small number of microphones have a real soundstage depth. I mean big part of live records (from 1970x - 1990x) and records done from 1955 to 1965. | |

| Tube amps - what 3 things… Hi @ieales, My friend does the same thing with 300B SET with Shishido schematics: ECC82 SRPP - direct coupling - 6F6 - interstage trans - 300B fix bias. The same excellent results. The ESR would be quite different with parallel caps... Yes y... | |
| Tube amps - what 3 things… Hi @atmasphere , In my case cathode resistor was 820 Ohm, so: with 100uF - f = 2Hz, 10000uF - f = 0.02Hz 100000uF - f=0.002Hz In theory, even 100uF is good enough. But in the real life the difference between 10000uF and 100000uF is very clea... | |
| Tube amps - what 3 things… Hi @ideal8592 , In my case 100uf/16v were Black Gate CE W (M). 10000 were the same Black Gate + Nichicon Muze 10000uf/16v. 100000 were the same Black Gate, Nichicon Muze + Nichicon KA 9x10000uf/16v + Elna 3300uF/10v It wasn't my "invention... | |
| Tube amps - what 3 things… Hi @atmasphere , I know that cathode bias is still cathode bias with any cathode capacitor value. But the cathode to ground impedance is realy very different. On 20 Hz with standard 100uF the impedance is Z=80 Ohm, 10000uf Z=0.8 Ohm, 100000uF Z=0... | |
| Linlai E 6sn7 tubes Can anybody explain in detail how do sound Linlai Global Elite E-6SN7 compared to Ken-Rad VT231 black glass? Do KR sound warmer and lusher? | |
| Tube amps - what 3 things… Cathode bias is not a good thing in input and driver stages, not just in the output stage. I tried one solution in my DIY SET 300B amp. There is 6sn7 input tube and 6F6G in triode mode driver tube with coupling capacitors between stages. The solu... | |
| Horn speakers with Imaging? Coaxial Altecs 604 with horn inside woofer have good imaging. | |
| Dennis Had Inspire PSE 300B WOW!!! Hi @tinear123, I am a DIY person. So for me is very interesting to know how this great amplifier is built. Can you give me some more information? What is the input and the driver tubes are used? Regards, Alex | |
| Dennis Had Inspire PSE 300B WOW!!! Hi @tinear123 , What is an input and driver tubes in Dennis's PSE 300B? Which rectifier and voltage stabilizers does it use? Is voltage stabilizers used for driver or input tube? | |
| Duelund speaker cable I used Acrotec 6n 1040 before Duelund. Acrotec it a old brand name of Acrolink. I bought Acrotec 20 year ago. It costed $100/1m bulk. It isn't a bad cable. But in my system (300B amp and Altec 604E), Duelund DCA16GA sounds more organic. Acrotec ... | |
| Duelund speaker cable I'm using DCA16GA for many years. Does DCA12GA sound just warmer or also slower? With which cable bass has better definition? |
