Spider IV - very nasty loud noise


Recommended Posts

I have a Spider IV 75, circa 2012.  It was unused for some time, then in trying it out, no response at all other than power on, display working correctly, white noise and crackle, and very very loud bang/cracks when I try to connect a jack.  I removed the top amp section, cleaned all the moving parts I could find, put jacks with contact cleaner in and out of any sockets.  The white noise and crackle has reduced a lot, but the 'big bangs' are still there, with no sound going through.  Connecting a device through the rear mini-jack is no problem, with no background noise, and output level controlled happily by volume.  So speaker and basic amplification is fine.  4 questions:-

1) Anybody recognise the issue and can point me to the likely culprit? 
 

2) Any recommendations to sites online to buy spares of boards etc? I'm based in SE Spain.

 

3) What's the likelihood of an experienced amp fixer (I am not one) being able to fault find and get parts?

 

4) Failing all else, any recommendations for price for a spares/repairs posting on eBay Spain? As I said, line in, headphone, speaker and amp and display all seems to be working happily.

 

Thanks for any help.

 

(PS I also have a Amplifi 150 that only lights up the ABCD voices dimly, but other than that totally unresponsive. Power supply or System board? Also cleaned it down, no luck)

Have a Line 6 authorized service center in your area check it out, there are five in Spain.

The first suspect would be cold or oxidized solder points on the processor or DSP on the main board. And have

them check tech bulletins for that. I would expect a couple of solder points to be oxidizing after this many years.

Thanks for this.  It's certainly been in a room which has experienced heat and humidity over the years. There are three service places on mainland Spain, and unfortunately they're all about 400 miles away from me! Do you think that a local repair centre (non Line 6) could check this out for me? Does anybody know if/where Line 6 sell spares eg complete boards? Thanks again

1) "Do you think that a local repair centre (non Line 6) could check this out for me?", not a good idea, as they won't have access to service info 

including any tech bulletins there might be for it, parts and me (or Yamaha in Europe) for any further advice they might want.

 

2) That is an old product, long time out of production, so parts would be limited, so what is still available would be for authorized service centers and repair.

OK, thanks for the quick response anyway. I'm not the first person to be disillusioned about the DNA of Line 6 commercial model I guess.  I have a 40 year old Peavey mixer amp and a 50 year old Carlsbro Marlin, both fully functional after local repairs with spares available. Unfortunately it seems as though Line 6 equipment is only designed and built to last about 5 years. You live and learn.

Spider IV line is much older than 5 years. And modeling products (whether L6 or others) are a different beast,

being both an analog and digital hybrid. 

 

Most generic products can get generic 1st party or 3rd party spare parts. And that's hard to do generic 3rd party 

parts when the product has lots of patented and proprietary elements in it.
