    TPA3118 60W Power Amp Module

    I have to buy a TPA3118 (the first one was a fake and I didn't try it!) but I still have any power supply 19/24v, and I don't know if or what I have to buy. I afraid about noise, of course.

    The heck is going on inside Jam Pedals Eureka?

    I want to add a pair of gutshots. One of the transistor is a BC107. And... Edito: There is more gutshot in this video:

    Adding a mid boost to chauffeur drive?

    I'm looking at the schematic of the Chauffeur Drive. I link it: https://docs.pedalpcb.com/project/Chauffeur-PedalPCB.pdf I never build it. But maybe you could try to put a 50k or a 100k pot in serie to the R5 22k. I'm experimenting something with emulatore, but you should try it somehow to see...

    That4305 issues

    A few of years ago I got (by Musikding) this defective module twice in a row. The pedal worked with the third module.

    My second Muzzle is worse than the first?

    Musikding sent me two new THAT4301 retrofit, before got it works fine. I'm not sure how, but I guess I got two failed chip. Then I wasn't sure if this new pedal worked so fine as my first Muzzle, but my friend was happy about it, and he tried the first one because it was for another friend we know.

    Boss DS-1 diy works wrong

    About mods... I really can't find the "trem mod". It appears in the Devi Ever forum, and I guess it connects two points in the circuit to get a sort o pulsing/tremolo effect, but I can't find the original image nor any description about it. Probably I will not include it in my building (never...

    Boss DS-1 diy works wrong

    What mods? All! I really getting fun with that, I'm still trying everything and I will include just the ones I like more, considering the space using a 1590BB enclosure. The mods I like now are: - Clipping: stock, LED, and asymmetric two LED and a silicon diode; - Mid boost: a pot in series of a...

    Thanks for the suggestion. I just inserted an NJM2904 in my Tayda's cart!

    Boss DS-1 diy works wrong

    I solved the issue moving the positive side of the diodes before the first op-amp stage from the feedback loop of that op-amp. (THe solution was in that link, indeed.) I still have a lot of volume, that is not a bad thing. The taper of the Distortion pot is not pretty identical to the original...

    Boss DS-1 diy works wrong

    I'm reading that page, thanks. My issue could be something about it. So I guess the problem maybe is something about the IC, even if I can't understand how other guys built it with satisfaction. I'll try to solve it.

    Boss DS-1 diy works wrong

    Hello, I'm building a Boss DS-1 replica with a lot of mods and fetures, just for fun. I built it on veroboard layout from here: https://tagboardeffects.blogspot.com/2014/10/boss-ds-1-distortion.html Schematic: I started from the stock project, with just a mod: I moved the jumper between pin 1...

    Germanium Transistors for Fuzzrite

    Yes, the one over 700, is very suspicious. Anyway, I'll try to measure it again, and see what exactly do and what value it reaches. :D I'll measure even the two around 170 a bit unstable. Anyway, yes, I'll test it with the fuzz circuit, just to see what happens. Thanks!

    Germanium Transistors for Fuzzrite

    I'm not sure. It's just those three. all the other 47 are stable. One has that very high hfe, over 700, I didn't wait until it stopped, but it was keeping going up, and not really slowly. The other two are have an hfe value pretty high, around 160, 170, but again, I didn't wait until that was...

    Germanium Transistors for Fuzzrite

    I got the transistors, and I started to measure the hfe. GT309B, with my multimeter, go from 85 to 182, those are 50pcs. But I found three weird measurement with three of them. A pair of those start from a value and keep going up slowly for several seconds. Another starts with a higher value...

    Low ESR Capacitors

    I use low ESR electrolytic capacitor, cheaper or good brand, in the power filter. For signal, when I really have to use higher value cap, common electrolytic caps. For a better performance I use electrolytic made for audio signal.

    Germanium Transistors for Fuzzrite

    I hoped I wouldn't worry about leakage, (somewhere else I read about leakage with pnp transistor couldn't be a problem, usually). But do you advice to select the transistors I'll buy by hfe and leakage? In this moment I have in my cart GT309B (60...180 hfe), and I have to decide about MP42B...

    Germanium Transistors for Fuzzrite

    I still need a little help, please. I'm starting to select my ideal range hfe transistors for Fuzzrite (but even more other fuzz, too, because there's a lot of pieces for just one fuzz pedal :D). Thanks!

    Germanium Transistors for Fuzzrite

    Thanks, Pedalbuilder! Do you mean that the hfe I read in the description is underestimated than the one I'll read then on my multimeter? For example: MP42B PNP ~AC128 OC75 - Forward current transfer ratio (hFE) 45...100, it could be... +10? +20? I guess that is important to choice the most...

    Germanium Transistors for Fuzzrite

    I'm look at this seller you mentioned, thanks. Well... I have to say a new transistors world is open in front of me. There's a lot of choice here. I'll buy some stock where I could have the fortune to find those hfe value. There's some particular transistor I could use in the Fuzz Rite circuit...

    Germanium Transistors for Fuzzrite

    Hello, I'd like to build once a Fuzzrite Germanium transistor version. But every time I stuck because I don't know where I can find a pair of good transistors. The original transistor are: Q1 - 2N2613 - PNP - hfe over 120 and Q2 - GN408 hfe about 65. Catalinbread Fuzzrite has a 2N404 and...
