I built it according to the design abov...Hello guys<br />I built it according to the design above. I can say one thing - it's Hellfire. The amount of gain it generates is amazing. Unfortunately, I did not have a few small components and I replaced the first 2M resistor with 2.2M, 30nF capacitor to 33nF, 20pF capacitor to 22pF and diode 4001 to 4007 (range up to 1000V). Therefore, I have a few questions. After setting the voltage on transistors Q1 to 7V and Q3-Q4 to 5.60V, the GAIN potentiometer works first like VOLUME - twisted to 1 (minimum) mutes the guitar signal to zero (nothing is heard). After a slight spin, the light CRUNCH begins and then at 2-2.5 GAIN is already saturated (like MAX in my Marshall Shred Master) and turning the knob to the end increases GAIN even more. The reduction of Q1-Q4 voltages to 4.75V caused that CRUNCH on level 2 disappeared completely (nothing can be heard), and GAIN starts from 2-2.5 already saturated. Additionally, turning the GAIN knob from 1-MAX raises the volume so that VOLUME is twisted on 2-3 ... Has anyone tamed this beast so that turning GAIN on Lev 1 gave almost pure sound but without muting the signal? Any item needs to be replaced? Maybe the 3.9k resistor next to the Q3 transistor should be replaced with a larger one (18k would be OK?)? Do you have any ideas?Thrasherhttps://www.blogger.com/profile/04329484215829847181noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-85851206752942336892020-03-29T08:30:25.133-04:002020-03-29T08:30:25.133-04:00This comment has been removed by the author.Thrasherhttps://www.blogger.com/profile/04329484215829847181noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-77187884477572921292019-11-06T09:21:57.683-05:002019-11-06T09:21:57.683-05:00This comment has been removed by the author.Ricco Seixashttps://www.blogger.com/profile/16351031394073802665noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-15497586903822294662019-11-05T21:59:31.605-05:002019-11-05T21:59:31.605-05:00Another successful project, great effect, here in ...Another successful project, great effect, here in Brazil I did not find original j201, I chose the 2n5457, I changed the potentiometer of A1M for 500k and had more drive, congratulations for the great site, I follow all projects here and on facebook.Ricco Seixashttps://www.blogger.com/profile/16351031394073802665noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-81012776143529643352019-08-15T15:51:11.269-04:002019-08-15T15:51:11.269-04:00Hello, how are you?
