Tīmeklis2010. gada 26. sept. · The best thing for you is to take 2N5486 FET's, for voltage gain, as so as buffer. Fet are just like the triodes (but only enhanced one's) I will give you … Tīmeklis2014. gada 12. febr. · It seems from reading various posts here that the Fetzer valve does its best imitation of a triode when not being driven hard, so I thought using it as a buffer would be ideal to add some quasi-tubish character to this pedal.

Tīmeklis2010. gada 17. okt. · "While the [Fetzer Valve 1.1] has its merits, we decided to further explore it to determine if it was a truly faithful solid-state version of the familiar input stage used in many tube amps." Over four years ago, the specific FET circuit you chose to test was deemed inadequate for not being sufficiently similar to tubes. Tīmeklis2012. gada 15. okt. · In this similar circuit I just made up, the drain resistor drops 4V resulting in 4.6Vce on the 5089. The 5089 transistors I have, has a current gain of about 500. J202 Idss is about 2 or 3mA. 3mA/500=6uA, so the drain resistor would be 4V/ (20uA + 6uA)= 153.8K or 150K. For 15uA Id, 4V/ (15uA + 6uA)= 190K. hotfix 2990941 download

Tīmeklis2006. gada 15. marts · Yeah, I got the Fetzer Valve working, but I don't know what was wrong initially. I had taken it off the breadboard for a few days then when I retried it it … TīmeklisWe would like to show you a description here but the site won’t allow us. Tīmeklis2010. gada 26. sept. · I've got Fetzer valve figured out, but I have no experience/understanding of buffers. 3. Do I really need the in/out capacitors in the buffer? How to they work (what do they do)? 4. Do I really need the 1M gate-source resistor in the buffer? Does it add any noise? 5. I like the 2N5457 in the fetzer valve, … hotfix 2998097
