I like the FF Not tuned for highest gain, but ability to get 'resolute' high gain and clean up at the guitar volume. as does the RM, then a TB, having it's 2 gain stages and 3 transistors fine tuned, should be a simple matter, both effects on and some more fine tuning. Having the FF which cleans up at the guitar Vol.
The booster/fuzz can also serve as 'Tonebender'.
2N3906 TRANSISTOR SUBSTITUTE FOR 2N1307 HOW TO
That way you can find a booster circuit which biases and sounds good with a transistor from batch which is most or.Īnd a Fuzz Face in similar fashion which utilizes the 1rst two transistor choices.įor both circuits the reads are at GEO, how to choose the transistors and bias them for instance. Now look at the data sheets of the potential replacements, and pick one with a good match. 2N1307 Transistor Equivalent Substitute - Cross-Reference Search. Forward Current Transfer Ratio (hFE), MIN: 60. So there is no such thing as a 'perfect' replacement - only one which is generally the same. Operating Junction Temperature (Tj): 85 C. NTE Electronics 2N3904 Silicon NPN Transistor for 4. BC547 and BC548 are functionally equivalent transistors. This will be used to drive power MOSFETs in a switch mode power supply. Given below is the list of popular transistors which can be used as a replacement for 2N3904: BC537, BC538, 2N4401, and P2N2222A. You could make 'perfbread' circuits, intended as something which could be 'finalized' by making some of the interchangable and trim components the fixed values you've chosen on the perfbread board. Notice that most values (leakage, hfe, etc) have a range of possible values. What I need is a replacement for a 2N3904 and 2N3906 in the same or similar package that can handle a little more current.
