..just sharing how I did my Behringer rehouse..

Thanks Bean, so regardless of the connections, be it connected - to +, - to -, + - +, the same formula applies.

..I understand the formula for 2 capacitors connected in series is
                     1
C total = ——————-
              1/c1 + 1/c2

..but what's the total capacitance value of capacitors connected in series with their like polarities connected...( creating a non polar capacitor)

Yes!!!.looking forward to madbean's fx90 release!..thnx in advance

Hi Brian..i still have the H schem sent by jMoreno...

..get well Rej !!!

Pardon me but i know this is not an overdrive...how about a buffer pedal with a little eq control so i dont need to run to the amplifier to change its tonal control whenever i change guitars...

Thanks Scruffie...the flanger works on its own after readjusting the clock trimmer..( i leave it on that position ) as if nothing is is defective...when power is turned off, then turned on again...it will no longer flange!...ill have to readjust the clock trimmer again to make it work again...yes it's hard to trace w/o schematic...
By the way, i already replaced some electrocaps...those 4 in horizontal position.

Note: as a i momentarily shorts the clock trimmer's pin 2 & 3 it works as it should...until the power is reset again..

Here's the gut shot Scruffie !....the vintage 117 flanger of course uses the SAD1024 BBD...

tnx for trying to help !

I'm trying to repair an MXR EVH flanger for my son's friend...when powered on, you can hear the LFO sweeping loudly...in bypass mode the sweeping bleeds also. The BBD chip, MN3204 works fine ( i guess ) because as i turn the clock trimmer clockwise all the way, then turn counter clockwise, it is now flanging 100% as it should...no audible changes heard when the bias trimmer is turned in any position.
    But as I reset the power...the flanging was gone, LFO again is heard sweeping loudly again....and when i repeat turning the clock trimmer as describe earlier...flanging now occurs normally.
   As the EVH boards is SMT, there's not much i can replace. I swapped out an MN3207 as it has the same pin config but has a higher delay stages...just to test somehow if the MN3204 is defective in some way. But same scenario happens with the MN3207. ( tho it "flange" in a different way ).
   Any suggestions where should i look. Tnx in advance.

I definitely will grab a set of the Eoo3 boards!...i noticed the 5v relays used are different from Linda.

46 days, 13 hours and 32 minutes

..Hi y'all....i understand that a 9v input on the road rage will render an 18v and -9v outputs. A 12v input will scale to 24v output, but will i get a -12v on pin 5 of the charge pump?

thanks i advance

Hi lars...i've got 2 diff vintage DOD90...one is working the other has dry signal but no delay...they have different trannys and capacitors value...i think i might need the schematic...would you mind posting it here or you can send it to my email...vidworks@yahoo.com
Thank you

Hi you all folks...my bass player friend has Behringer BDI2 and asking me he needed more on the presence knob and more lower end on over all tone...please advice which resistors/capacitors should be replaced...i know Behringer BDI21 is a copy of the SANSAMP Bass Driver..so here is the schematic of the latter...thank upu guys in advance...
