| Dynaco PAS 2 value and difference to PAS 3? Emorrisiv, here are some tips if you are interested:try to retain the rectifier tube. Replace all the filter capacitors. Replace the selenium filament rectifiers with 3A low voltage silicon devices.Tape has become more popular, but usually the tap... | |
| Tubes vs. solid state. Hi Sam, IME the most transparent systems I have heard are also some of the more relaxed, but of course I have heard many systems wherein 'transparent' equates to 'analytical'.This has to do with the types of distortion the system makes. If the hig... | |
| which is better ? MC phono stage or MM+step-up ? Emorrisiv, have you been playing with loading? | |
| Wilson Audio's New Sound? Wilson has always designed his speakers to be tube friendly and the current crop is no exception. I've heard the Sashas several times recently and they do quite well with the human voice yet play the frequency extremes easily. Plus they are effici... | |
| DCS Puccini into Lamm M 1.2 w/o preamp? Martin, FWIW we have customers that have the dCS and they own our preamp for the volume control even though they could go direct. I think the 'cold and clinical' comment above was the reason our customers got a preamp. I don't think the preamp war... | |
| Parallel Triode amps vs Triode wired pentode amps Jeff, pentodes wired as triodes are not the same thing as actual triodes. It is not that hard to put triodes in parallel; there are techniques for that and the linearity you get is still well ahead of that of a pentode wired as a triode.This only ... | |
| Top ten tube preamps The reason I use tubes is not so it sounds like it does! I use them because you can't tell what is in the preamp- nor would you care- its all about the music.I would use transistors if I thought I could get this same quality but so far its not bee... | |
| Amplification for Wilson Watt Puppy 7s or 8s FWIW, the Puppy woofers don't need a lot of 'current'. John Giolas, the national sales manager for Wilson, used our amps for years on his WP7s and 8s. You have to understand that at Wilson, you have your pick of almost any amp you want, and you do... | |
| cleaning the pins of NOS tubes...bad idea? The **most** I ever use is a simple contact cleaner like you get at Radio Shack. After cleaning the tube pins, I wipe them down to remove all excess. The reason I am careful about this is it is very easy to contaminate the base of the tube and/or ... | |
| which is better ? MC phono stage or MM+step-up ? Brent, All transformers have a primary and secondary winding (if they only have a primary then they are called autoformers). The windings do not care if one side is at ground or not. So at the input to the SUT, you could lift the winding connectio... | |
| Top ten tube preamps Exactly- that is what I find too. | |
| DCS Puccini into Lamm M 1.2 w/o preamp? All the dCS units I have seen employ digital volume controls. If you have one keep in mind that as you reduce the volume, you are also reducing the resolution. That is why its often a good idea to consider a preamp with a good analog volume contro... | |
| Top ten tube preamps IMO/IME when you go for synergy its one coloration counteracting another- not a good way to go if you really want neutrality. I recommend choosing equipment on its strengths, if that makes any sense. | |
| Dynamic Headroom In a Class A amp the output devices do not go into cutoff within the amp's linear region. Sure, you have the amp biased heavily, but that does not affect output voltage. Many people are surprised to find out that the bias point does not affect the... | |
| which is better ? MC phono stage or MM+step-up ? Emorrisiv, one thing you will find in working with cartridges in general is it is best to keep your connections between the cartridge and the preamp to a minimum. In the case of an SUT, I think you will also find the cable **after** the SUT to mor... |
