| High value, high efficiency speakers for SET amps As discussed many times SET amps need a very well designed power supply so they can handle dynamics and bass as well as they handle midrange. Even a small change in the design of the PS can either improve or detract from how the amp handles bass a... | |
| High value, high efficiency speakers for SET amps Rebbi,One thing I have found about orchestral recordings is they vary quite a bit in recording technique. Some sound like they were recorded at the first row or actually from the conductor's seat and some sound like they were recorded way back in ... | |
| High value, high efficiency speakers for SET amps Tonight I was listening to Walton's viola concerto, Bartok's concerto for orchestra and some rock music shaking the floors. Finishing the evening with Johnny Hartman and John Coltrane serenading me - each of these genres is handled convincingly. S... | |
| Elrog 300B vs Takatsuki 300B tubes Matthias, Thank you for sending the schematic. | |
| Elrog 300B vs Takatsuki 300B tubes Matthias, Were you able to find the operating points for the AudioNote Quest? I was looking on line and could not. | |
| High value, high efficiency speakers for SET amps Rebbi, Today some older version AN-e's came up for sale here on Agon. Very good price and the AN stands are included. By this point you may have written AN speakers off of your list but wanted to bring them to your attention. On another more aspir... | |
| Elrog 300B vs Takatsuki 300B tubes Matthias also brings to the table an interesting observation about the current draw of 1.5 amps for the EML 300b XLS. It is 25% higher than a standard 300b which is 1.2amps. This is something I have mentioned in these pages to folks who were consi... | |
| Elrog 300B vs Takatsuki 300B tubes ...and if the franks are set up to run at 413v @ 87mA. Many would say that's running 300b tubes pretty hard. | |
| Elrog 300B vs Takatsuki 300B tubes I did not expect to hear that the Franks are indeed running 400v on the plate. That puts them towards the upper range and not a conservative operating point. I would think that's the upper range of what the Elrogs can handle. No wonder the EML 300... | |
| Elrog 300B vs Takatsuki 300B tubes If the power supply is outputting somewhere around 425V that would mean the 300b tube would see a more conservative 325 to 350v acoss the plate depending on the cathode resistor value. | |
| Elrog 300B vs Takatsuki 300B tubes Charles I agree there is some confusion going on. A call to Israel will solve this. I would guess the Franks Power supply is outputting more or less 425v. And if it is somewhere around 425v no adjustments to the Cathode resistor would be needed. | |
| Elrog 300B vs Takatsuki 300B tubes Charles you may want to call Israel Blume. I find that this operating point would be hard to believe. It would fry any mesh plate tube and push any standard 300b to its limits:"1kOhms cathode resistor we have 86.8V at the cathode at anode current ... | |
| Elrog 300B vs Takatsuki 300B tubes The franks have a very high operating point!?- 525V operating voltage with some drop (25V) over the OPT- Makes 500V at the Anode- because the 1kOhms cathode resistor we have 86.8V at the cathode - results about 413V across the plate of the Elrog. ... | |
| Capacitor log Mundorf Silver in Oil Thanks Justubes for the detailed response. I have printed this and will refer to it often. | |
| Capacitor log Mundorf Silver in Oil Justubes2, Could you fill us in on your bypass cap values?Lets say you have a 22uf cap in your power supply, what values and brand would you choose as your bypass caps? Thanks jet |
