| New Aluminum Platter from VPI Hi Bob, I'll add that thread drive and tape drive are both somewhat tweaky-- requiring correct selection of threads, knotting & splicing techniques, and precise tensioning. They are not plug-and-play like the soft rubber belt. My guess is that... | |
| New Aluminum Platter from VPI Johnbrown, What custom pulley are you talking about? Having experimented at length with custom pulleys, I can report that some pulley designs add more problems than they solve. And there is nothing wrong with the Hurst motor-- unless you are dismi... | |
| Capacitor log Mundorf Silver in Oil As the thread moves into the rarefied air of CAST, it would helpful for Duelund Coherant Audio to share some specific models of commercial loudspeakers that use CAST. This would give more DIYers and audiophiles the opportunity to hear these caps a... | |
| Useful Life of PreAmp Tubes. Elevick, It's difficult to generalize, as the life of a vacuum tube is determined by plate voltage and bias applied in situ. In my system the same model of 6SN7 tube can last 2k hours in one component, and up to 15k hours in another. | |
| Retubing power amp Ditto Samujohn's referal to Jim McShane, from whom I've purchased Tung Sol reissue 6SN7 & 6V6, and Sovtek 6H30pi for VK75SE. NOS 6H30-DR are NOT worth the $$$. Buy 6C33C-B in bulk from cheap eBay Eastern European sources. | |
| Useful Life of PreAmp Tubes. As best I recollect VK5i does not have a stand-by switch. In any case, I always powered off when not in use for more than several hours. Victor at BAT will likely respond to a direct query. | |
| Useful Life of PreAmp Tubes. I retubed VK5i about every 2k hours and always heard improvement. Preamp tubes may survive for 10k hours, but not without sonic degradation. | |
| what is the quietest air pump for my ET-2 ? Even pumps marketed as whisper quiet typically have >30db noise. I don't know what pressure/flow rate the ET arm requires, but but if you are getting by with a low pressure pump, there is no reason to add the complexity, condensation issues, an... | |
| BAT VK75 Tube placement? I forgot that non -SE version uses two 6SN7 in lieu of 6H30 in input stage(first row.) That is where you should hear the greatest difference with your NOS tubes. | |
| BAT VK75 Tube placement? Victor wrote me that all six 6SN7s perform the same function and close matching is unnecessary. These tubes take 600V at start-up, which may be a problem for some types. I'm not much into NOS tubes; IME Tung Sol reissues surpass EH. The unit can b... | |
| Alejandro Escovedo Live at Mc Cabe's Real Animal is a very good album. Its only weakness is congested & compressed production, even on vinyl. Amazing how stripped down unplugged sets like the one you saw at McCabe's can bring out the best in very electric bands(e.g. Nirvana, Alic... | |
| New Rowland Criterion 2-chassis battery pre Did UPS extenze his signature pad or twas Bruno with his silver codpiece and knit legerhosen? No ohmygosh it's JRDG rounding the corner. | |
| VPI Scoutmaster Super Platter Or perhaps a TT Weights copper mat on top of the existing platter, with or without his carbon fiber layer, clamp, and periphery ring system. That adds 4 lbs. of rotating mass, in addition to other beneficial effects. The copper mat improved my TNT. | |
| Best cable for Jumpers I don't know what type of binding posts B&W uses, but if the nuts come off, excellent jumpers can be made from electronics-grade copper foil with holes punched or drilled through to the diameter of the posts. Solderless, minimal metal mass, ne... | |
| Merlin owners who have modified x-over? Claritycap MR and Duelund resistors were broken in and evaluated separately in each section of the crossover. The MRs sound great across FR and are claimed by design to have internal resonance control characteristics similar to Duelund. Duelund gr... |
