Re: Dunlop - Octavio

8k, 220k and 5k & 500K pot values verified? fuzz pot is B5K, volume A500k R6 is 220k and there is no 18k resistor hi there, anybody tried that pedal with the TM011 transformer with the 1:3 ratio? I change Q3 from BC549 to MPSA18 C8 from 4700pF to 1000pF C5 from 22mF to 47 mF Fuzz pot from B5k t...

Re: EVH phase 90 resistors values

Thank you Bside2234! This is Dunlop marketing to sold one same pedal as three different. New dunlop 90 phasers (except 74 reissue) are made on one double side smd pcb, marked as EVH phase 90 Rev.B. Numbers of components on this pcb not the same as in older versions. R5 & R6 on this pcb are both ...

Re: EVH phase 90 resistors values

I trace this problem. R5 & R6 are both R28 mod resistors stay in parallel and be connected one or another by SPDT switch between second phase stage and R34 & 7 pin of IC2. It means one of them is 20-24k but another???? What for it is necessary???

Re: EVH phase 90 resistors values

New dunlop phase 90 script edition CSP-101s/sl made on one pcb as EVH phase 90 (Rev.B). It (CSP ed) has switch button on pcb which doesnt work and there are two missing resistors marked R5 & R6 (numbers not the same as in older schematic). This push button switch between Script and Block mods in...

Re: EVH phase 90 resistors values

Ok, guys. I have one, but csp-101 not evh. I want to modify it to evh, because it has the same pcb (smd version) only missing resistors R5 & R6 (R28 mod). I guess they are both R28 (1/2 R28 each) or only one of them is R28. i cant accurace trace it because there are many big details on pcb. I as...
