| is getting a tube pre a valid option with ss amp? OK- Component limitations are getting confused with engineering concepts. Ganged tubes can produce lower impedance outputs and high power levels. Same with transistors. We all know that. It has nothing to do with what I said. The condensed version... | |
| is getting a tube pre a valid option with ss amp? More tubes are required if it's a line stage + phono preamp combo. That is the only exception. I have seen basic preamps with a single tube that work exceptionally well. A single tube, set up correctly has considerable gain. Most amplifiers have e... | |
| tube burnout Sounds allot like either a filament or high voltage supply design flaw or defect due to a blown part. It would not be difficult to modify or repair. | |
| Questions about Preamp Tubes Small signal tubes, like the 12AX7, etc.. do last considerably longer than tubes such as the 6L6 in most cases. I wouldn't worry about how long they last because they can go on for years. Small tubes are replaced more often because of defects rath... | |
| Name brands that are not so well known are skipped Actually, I don't believe small businesses deal with proprietary parts as much as big businesses. If specialized components and complex circuits are a concern, it's best to stay away from large companies. Something else: I would have to believe a ... | |
| Name brands that are not so well known are skipped Hopefully most businesses will have a web site with an 'about us' page in order to help people learn about their background. A good deal of the time people starting new businesses in audio electronics will have some prior work experience in the el... | |
| Name brands that are not so well known are skipped The beauty of tube technology is the ability to produce circuits that are easy to repair. Equipment that is point to point wired has the highest potential to make it through the ages regardless of who made it (as long as it was properly made). The... | |
| Name brands that are not so well known are skipped Tvad: Your point is well taken! I was making a generalized statement meant to help out all the new builders and people with specialized equipment who frequent Audiogon to post. There's so much to choose from- but folks have to click on it to see w... | |
| is getting a tube pre a valid option with ss amp? Adding a good, basic tube preamp will increase the presence and sound stage of your system. At one time I didn't believe that it would make any difference, but now that I have tried it, the difference is huge! I say basic because preamps with allo... |
