Hi,
I've worked several hours on this project and it's totally verified, it work perfectly and is pretty close to the original Dove but as I haven't plugged my axe on the original one I just can say it in comparison of what I've heard on the differents demos available on the net...
I have to tell one more thing, it's the rectifications I have to share for this project works perfectly, so here we go:
Q1 & Q2 for correct amount of gain use 2N5458 or J201
Q3 & Q4 must be, according to your taste, NPN Ge trannies Hfe 80/110 (Q3) and Hfe 50/80 (Q4)
IC1/2/3/4 opa2604 or opa2134
The deep switch resistor should be 680Ohms to 1.5KOhms according to your taste
And for the unknow caps values here are those I used, you can try another values but these ones makes the job perfectly!
C2->220nF to 470nF / C5->100nF / C7->68nF / C8->220nF to 470nF / C11->68nF / C12->220nF to 470nF / C16->330pF / C20->470nF to 680nF / C22->220nF to 470nF / C23->220nF to 470nF / C24->47nF / C28->47nF / C36->100nF / C39->100nF
Let me know if you find other values which works better...
(And I'm always looking for the pics of Dove solder side pcb)
Happy new year to all of you guys!!
Alex.
