I recall the original Yerasov page contained way more files than the 14 listed at ESI. Anyone recall it beng so, or is it just me? I have a Yerasov Gamma FC-1 F.E.T. Color i loaned from a friend and i thought i'd ask if anyone has seen a schem before trying to trace it. With the gate section i'm qu...

Success!! Checked the voltages again today, and noticed the VTRIG was slowly dropping over time. I removed the SMD cap in CE9 position and replaced it. VTRIG rose to around 8.1V and the pedal came to life! Thank you so much deltafred for your help. I making a collection of this pedals, please post ...

Sorry for the double post but, I fixed it... I tried to replace the switch and didn't work, replaced it by a jumper and didn't work also. The jumper was shorting a via hole. Now it's working. I hope you like the pictures, let me know if you need something from the pedal while I still got it!. :mrgr...

You have all of this?? PCB please post all you have! thanks!!

The first version, the original unit that sounds so 'special' and good!! I've read the discussion between the 'Made in the UK' version and the 'Made in Korea' version, so I just put the two together. Made in the UK: DSCF4173.jpg Made in Korea: DSCF4172.jpg The values are all the same; the IC is in ...

Please LUKATOSH are you there??? her e is my suggestion to do what you proposed; take a time and let me know it is right or not!! and please the values of the part for the BOOST section??? THANKS a lot man!!!

well, there's definitely not a 1M from gate to ground in this pedal. I just traced it out in mine. here's a pic of a mirror image of the bottom of the board with the component labels on it as they are on top of the board. you can clearly see that there isn't a 1M from the gate to ground: [ Image ] ...

PL has a lower clipping level, much lower gain though. i find the curve control really muddied up the sound, you have to blend the clean stage in about 1:1 to get it a bit clear. Had just finished a double sided layout for 1590B enclosure if anyone interested (a bit cramp). I haven't build it mysel...

Please man more PHOTOS of the solder side!! and the parts side please!!!

Ok, these are quite old, I had newer one, with fatter tracks and pads, few ad-ons like jumpered output resistor, or added pads for 4th transistor wired as a diode, and generally more charming - but I can't find it, I have a mess on my hard drive These are layouts for quite a few MK3 variants includ...

Please someone a single sided PCB??? PLEASE man!!

I finally got mine finished , after having a few issues, sounds great and happily not excessively noisy. Still have one strange issue , running at 18v from my power supply it pops and cuts out but at 12v it works and sounds great. I've checked all IC and they are all ok with 18v so not sure what to...

you have the LIONSOUND 14?? please post all you have PCB; layout; external connetions!! thanks!
