juice Posted March 24, 2009 Share Posted March 24, 2009 (edited) hi, I have a Line-6 DM4 distortion modeler which has packed up on me. As it was rattling I opened it up expecting to find a loose chip. What I have found is a component labeled 330fu which looks like a resistor of some sort with wire wound around a central core it appears as though it is covered in a silicone type blob. The position on the circuit board is marked as L1 on the main power in section. I would love to get it repaired but Line 6 haven't contacted me despite 2calls a week for 4 weeks! thanks for any help you can give juice Edited April 29, 2009 by juice Quote Link to comment Share on other sites More sharing options...
neilb Posted March 24, 2009 Share Posted March 24, 2009 can you post a photo? Is it 330 fu OR uf? If its uf, then its probably a capacitor of sorts, altho I agree the description sounds more like a resistor. Quote Link to comment Share on other sites More sharing options...

PM me if you like and I'll have a go at fixing it. No promises though. Quote Link to comment Share on other sites More sharing options...

I would guess from looking that the base part appears to still be on the board & there is no holes through the board so i guess it mus be soldered on the top somehow? by the fact that I can see the wire coil which i presume was 'inside' the component it has come apart. I wonder if it would be normal to apply this silicon type blob? It is probably to small to photo but will try when my cameras charged up thanks for your help so far Quote Link to comment Share on other sites More sharing options...

Anyone with some soldering iron skills should be able to sort that out. Dave Quote Link to comment Share on other sites More sharing options...

It might be a surface mount component (SMT) in which much harder to fix without the correct equipment. Ring Line 6 would be my advice.

Dave[/quote] Thanks for your help Dave I will keep trying to get through to line-6, I wonder if anyone has an email address for the repairs dept.?

juice Posted April 11, 2009 Author Share Posted April 11, 2009 I have had direct contact with line6 uk now who have been very helpful and will repair unit for me so off to the post office on tuesday... thanks to all for your help. juice Quote Link to comment Share on other sites More sharing options...
juice Posted April 29, 2009 Author Share Posted April 29, 2009 I have just got back from working in Italy - DM4 has come back from Line 6 fixed & serviced.... I'm a happy bunny! Quote Link to comment Share on other sites More sharing options...
