last resort........








if all still not working, please consider to buy a new pedal.. or build one........  :icon_mrgreen:

Ok Diode is still ok but that 12v regulator is blown. Are you saying with that blown it may have caused additional damage down the line and it is not repairable?

Thanks all for helping out.

Nothing is for sure right now EXCEPT the fact that you have identified a bad 12V regulator. That needs to be dealt with BEFORE moving on.

Did you get my PM?

Big thanks to Greg for helping me out on this. Put in the 12v regulator ( ;) now I know what it is ) and whamo Flanger back. Now I do not have the light working, LED so I do need some help on that. While the unit was down I did try a 9v battery on the LED to see if it worked and it did... hope I did not fry that? Any thoughts.

BTW, just a note of special thanks to Greg and a forum that is kind and civil.

PS on a one spot, is there a tip that will work with this unit?
PPS I cannot make out the symbol of the LED on the schematic?

angelodp

Ok so the pedal works but not the LED. Took out the protection Diode and it is working ok out of circuit. In circuit it is passing voltage in both directions. I think the problem may be a sloppy soldering
job done by a tech a while back when he was trouble shooting the pedal... never did fix it. But it looks like the solder has slopped over and is making some bad connections. Not sure how to get that solder out of there . I have tried braid and
solder sucker but a thin sheet remains and is making contact where it should not... I think.

Any suggestions would be great. The pedal works.


Govmnt_Lacky

Your best bet would be to remove any questionable solder with either the braid or a solder sucker. Do this the best you can. Then, USING THE SCHEMATIC.... cut or remove  the "bad" traces with an exacto knife. After you have confirmed that ALL of the "bad" traces have been severed (ensuring connections are good in accordance with the schematic).... then resolder and re-check.

Odds are that the traces that are UNDER the boards coating are good. You just need to worry about the "questionable re-work" that was done.

Good Luck  ;D

Greg, yeah it was the LED, threw a new one in and its all back to working like new. Now the One Spot tip is still a question. AFAYK ... does this unit require a positive tip or negative tip power source.

Thanks  Ange

Should be easy to find out. Just check for continuity with your DMM from the input of the 12V regulator (the leg that reads 18V... which SHOULD be the leg closest to the DC jack) to either the DC jack tip or outer ring. That should tell you if the tip is V+ input or the ring is V+ input.

BTW... do this with batteries removed and no power applied.

Good Luck  ;D

Hey guys, I too have a FL-301 problem that I haven't really dove into yet.  I have checked the debugging page and it doesn't cover the issue that I am having.

The issue is, I have a substantial volume loss when I use this pedal "on" AND bypassed.  I know this pedal isn't true bypassed in bypass mode, so the issue is happening in circuit somewhere. 

Any idea what in the world this could be?

Thanks,
Chuck
