I just finished this layout for the FL9 flanger. The resistor and capacitor names are from the schematic at http://www.mojotronics.com/images/FL9.pdf
Q1, Q2, Q4, Q5, Q6 - 2N5088
Q3 - 2N5087
IC6 - 5 volt regulator

The PCB is 85mm wide by 73mm high. Again this is unverified so feel free to scan it over and make sure it's good before embarking. I'll probably try to build it next week sometime. Hope someone can use it!
the schematic is just the same as BOSS BF-2 more or less. Not for JET flanging I guess..
michael, have you verified this?
maybe i will build this instead of the MXR Flanger, because i can't find any SAD1024 in europe.
has this been verified by anyone? looking to build a fl9...

Same here, has anyone built it?
i built it, it's good. nice and subtle
Ok so it's good. What is the parts list? The schematic print is a little hard to read. :-\
Bump.
Yep, the parts on the schematic are very hard to read. Does anyone have a clean copy of the schematic?
BUMP again.
Gonna try to get a parts list from the "fuzzy" schematic but if anyone wants to save me the time and link a parts list.... that would be swell too! ;D
Also, has there been any other validations of this layout?
OK.
I worked out a parts list from the schematic above ;D
There are a few parts that I am not 100% for sure about BUT I put my best interpretation of the number on the schematic into the list.
Also, there is one resistor MISSING on the layout when compared to the schematic PLUS there is a trimer on the layout that is not on the schematic.
I would really like another set of eyes on my parts list. If anyone wants to volunteer I will send you the Excel list that I made.
Any takers??
Good work Govmnt_Lacky, I'll definitely take a look. I also own one of these pedals so I can provide gut shots and any further information you need.

Please post 'em
No problem. I'll post them when I get home from work tonight.
Apologies for the delay, here are the gut shots as promised.

Hi!
Nice work!
I will do it, but I can't make it without the part list.
Can you send it to me?
Thank you!
Finished the parts list!
Etched the board!
Still waiting for some 1% resistor values for this project :icon_cry:
Going to build this up as soon as they come in.
Noticed another problem with the layout. R116 (schematic) or R16 (layout) is missing!! It is the 56K that goes from the MN3207 Pins 7 & 8 to GND. This resistor is easily added to the layout above.
Will report when I get it on PCB and testing has begun ;D
Can anyone explain to me why VR104 was added to this layout?
I see that R63 and R64 are set up as a voltage divider to provide the 4.5V VRef according to the factory schematic BUT..... why was the trimmer added ???
Couldn't VR104 be removed and then just add a jumper from Lugs 1 & 3 going ot Lug 2?
Need a sanity check here.

This is an interesting fact. I recently built this and immediately noticed that the ALL of the pots are wired REVERSE! Also, that trim pot (VR104) is not called for on the schematic. Also, you are missing a resistor from the MN3207 Pins 7 & 8 to ground!
Did you verify this but fail to post any of the changes?
I am still working on getting my LFO to wobble. All else seems fine as I get the "warped" sound when adjusting the Width and Delay pots but, the Speed pot is non-existant and I get no voltage swings on my LFO IC pins. I used a TL022CP as called for on the schematic. I am gonna try different Op Amps and see if I can get it to "turn over!"
I also matched (2) 5088 transistors to replace the 2SC2583F that is used on the original units. I matched them at an Hfe of 510. I read in another thread that maybe they should be tested for Vbe but I am hoping it is not that strict in tolerance.
Finally got this boxed up and working! ;D
There are some changes that need to be made to the circuit AND the layout that are very simple BUT... it is a GREAT flanger. The bonus is that you don't have to get the SAD1024 chip to get great flanging and it seems just as adjustable as the MXR M117 ;)
I developed a parts list from the factory schematic so if you need it, PM me with an email address. The list is on an Excel spreadsheet and I am too lazy to re-type it here :icon_redface:
Thank!!! Govmnt_Lacky.
I'm Beginner. i built form this layout Regen,Width ,Speed, is work now ;D.
But this Flanger i feel the sound is weak ??? Anyone Help!!!

What do you mean by "Weak?" This flanger is not going to sound as deep as the M117 if that is what you mean. You are just not going to get that with a 3207 BBD.
I built the FL9 for a friends son for a birthday present. He runs 9 volts on his pedal board so...shy of putting together a build with a charge pump voltage doubling circuit....I'm kind of strapped to building him lower voltage effects.
My opinion of this flanger????
It doesn't sound bad. This is definitely not an ADA flanger! but...not bad for what it is.

Here's my redraw of the schematic:

One other thing of note:
Some of you might remember a thread were I compared the dual 2SC1583F with two matched 2SC945Ps.
http://www.diystompboxes.com/smfforum/index.php?topic=103921.0
There wasn't much difference at all so....the difficult to obtain 2SC1583F can be replaced with 2SC945Ps.

There's a schematic available a couple posts above yours (though I'm sure you've noticed?). I'd use armdnrdy's schematic and his suggested work-around part to save yourself a part-sourcing headache.

Ofc, i saw it, i asked him for a parts list that he used , schematic and layout changes with success with the pedal, also thanks for the referance, i learn new things everyday in this forum :)
Hi, I've finished building my FL9 clone flanger, it works perfectly and sounds very good :icon_biggrin: .
I made a recording to demonstrate how does it sounds like. I'm not a guitarist, so I used a synthesizer,
the roland jupiter 6, then a string machine and a song. Hope you like it! :icon_wink:
Really thanks to Michael Allen and Govmnt_Lacky!
