2022年6月21日 · Are you saying you want to build a 2 stage amplifier, 6SN7 into 6V6 outputs? That's perfectly feasible. I just posted my circuit for 6SN7 into 2a3 in another thread and I've …

2004年4月23日 · this is my first time posting here. i have a pair of 6SN7GTBs and a pair of 6V6GTY tubes. i want to try building a SET amp preferably tube rectified using 5U4G. i'm …

2011年9月24日 · I would recommend you explore changing the 6SN7 to a 6SL7 if you want more gain before the 6V6 output stage. This is by far the easiest way to do that "experiment". see …

2023年12月17日 · So I decided to use a 6SN7. With it’s low µ and very low noise it fits the needs for this driver very well. The 6V6 family (6V6, 7408, 6AQ5, 6005, etc.) can be a little cool in the …

2008年6月13日 · There are some early organ amps that use 6SN7s on the front end. The difficulty there is that a weak B-3 hits the first preamps stages with around 4.5 volts of signal while the …

2019年3月18日 · 6V6 can pass 100mA and throw 12W of heat. Each half of 6SN7 can pass 20mA and throw 2W. For a good fit you need a load impedance like 100/20 or five times what a 6V6 …

2025年3月16日 · This is a fairly straight forward 6V6 SE UL design with a 6SN7 driver stage (unbypassed cathode). Peak undistorted power is 3.2W RMS into 8Ω. Input sensitivity is 1.56v …

2013年6月19日 · I have a chassis and the necessary iron (including choke for power supply) to build a STEREO basic amp with 2 pairs of 6V6's in push-pull. I have on hand an Arkay A12, …

Here's what I'm thinking...get a 10 watt OPT that's meant for 6V6s and run two 6SN7s per channel in a push-pull parallel set up. That would give roughly the right impedance for the …

2013年2月25日 · I recently purchased a 6V6 push pull power amplifier which has 6SN7 as the pre-stage. I would like to increase the gain but do not want to void the warranty. Does anyone …
