Tīmeklis2024. gada 19. sept. · If I want to run at 12V or 19V (I have these power supplies), should I just use the calculators on the ROG Fetzer Valve revisited page after working out the Vp and Idss for my MPF102? The values in the schematic are twice that of the average values on the ROG page. Print. Go Up Pages 1 2. Tīmeklis2004. gada 21. sept. · Here's what he had to say about this Fetzer valve schematic. It acts more like a DI circuit.... a JFET having a high input impedance and low impedance output. So the JFET acts like a variable resistor, varying the amount of 9V power corresponding to the input signal coming from the guitar.
J201 sub for a 2n5457? PedalPCB Community Forum
Tīmeklis2024. gada 9. okt. · Big Monk. Well-known member. Oct 8, 2024. #2. My immediate response would be no. J201, on average, will have much more gain than 2N5457. Here are values from the RoG "Fetzer Valve" article: I'm not sure what the potential 2x boost in gain will do to the circuit.

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.
