[QUOTE="Telmar, post: 162586, member: 4611"] [B]The 800 Module:[/B] The Marshall 800 design makes use of three stages only to get its gain, and a fourth stage that connects the bare preamp with the EQ section. This fourth stage is a bit special, because it's called a cathode follower and provides no gain at all. Some manufacturers add it in front of the EQ-section, because it is able to deliver a lot of current and with some EQ-designes that makes absolutely sense. And it adds its own color to the sound. Did you count the stages with me ? Three for the gain and one for the current. What does the fifth stage do ? As I mentioned above, I did not reverse engineer a Synergy-module so far. So be cautious at this point, because I start to assume, even I was told not to do so when I was an apprentice some decades ago. Tubes vary very much in their values, unless you buy selected or even matched tubes. Usually selected means the tubes are in a certain range, and matched means the company who selected them tried to find two or more tubes that are as identical as possible. You can even buy tubes where they tried to find a tube with their two systems in a glass bottle that are as identical as possible (very laborious and even more expensive). So just look at the graphs and at the modules pot positions. Not very identical, right ? I think this is caused by switching not just two sets of pots in and out, I think this is caused by two slightly different gain stages ! The reason for this might just be two different tube stages, as I lined out above, or slightly different designs of a specific Red and Blue tube stage that is A-B-switched. [/QUOTE]
