richrips Posted November 9, 2015 Share Posted November 9, 2015 [color=#282828][font=helvetica, arial, sans-serif]Hi All,[/font][/color] [color=#282828][font=helvetica, arial, sans-serif]My Ashdown little giant 1000 has worked flawlessly since I got it 7 or 8 years ago. Last night It made some funny sounds like a lead being disconnected badly then stopped producing sound although the bass was still showing up on the preamp visual meter. I changed the speaker cable to the other speaker output and it works. The trouble is I have a gig on saturday and will need to use 2 cabs. Does anyone have experience repairing these? Is is worthwhile? I'm handy with a soldering iron but I don't want to waste time if this is doomed. Meanwhile I'll be searching for someone to send me a new (used) amp to use at the gig.[/font][/color] [color=#282828][font=helvetica, arial, sans-serif]Any help much appreciated.[/font][/color] [color=#282828][font=helvetica, arial, sans-serif]Cheers![/font][/color] [color=#282828][font=helvetica, arial, sans-serif]Ric[/font][/color][color=#282828][font=helvetica, arial, sans-serif]h[/font][/color] Quote Link to comment Share on other sites More sharing options...
Merton Posted November 9, 2015 Share Posted November 9, 2015 I suspect the power module Ashdown used in the LG1000 is no longer easily available but easiest way to find out would be to fire them an email. As for cabs - what impedance are they? You can run two 8 ohm cabs fro one side no prob Quote Link to comment Share on other sites More sharing options...

Matt P Posted November 9, 2015 Share Posted November 9, 2015 if I remember right these have a pair of power amps in them, one running each output, it sounds like one of these has given up the ghost, I know that Ashdown had some quality issues a while ago (manly with the power section of the Superfly) it might need a new board, I would get in touch with Ashdown customer service, there's also a sticky in this section with amp techs, there should be one near you who could advise as well. are your cabs 8 ohm or 4 ohm? if they're 8 then you can daisy chain them from a single output (assuming they have 2 sockets each) and it should give you a similar output to running one speaker from each output.

buff Posted November 9, 2015 Share Posted November 9, 2015 Could be something as simple as an input being worn, has it ever been serviced. you could always take it to Russ Fletcher in Camborne to be checked out. Quote Link to comment Share on other sites More sharing options...
richrips Posted November 9, 2015 Author Share Posted November 9, 2015 Hmmm ok that's interesting. I'd not considered daisy-chaining cabs. My cabs are 8 ohm only have one 1/4 inch input each. Can I make up a cable to run both from one speaker output? Had a few offers of amps from my wanted ad but cash and time are both issues. Little worried about trusting half an amp for the gig now!

buff Posted November 9, 2015 Share Posted November 9, 2015 You could get a splitter cable, I've a ashdown spider/touring head for sale in the amp section. It's not exactly lightweight, but I live locally. Quote Link to comment Share on other sites More sharing options...
Matt P Posted November 9, 2015 Share Posted November 9, 2015 what speakers are they? is there room on the output plate for another socket? adding another socket is a fairly easy job, about 5 minutes work with a drill; a bit of wire and a soldering iron. you'd only need to add the socket to one to allow you to daisy chain the cabs.

MoonBassAlpha Posted November 10, 2015 Share Posted November 10, 2015 It may not be the amplifier section at all, may just be a dry/fractured solder joint from the noise described. Some annular solder fractures can be quite hard to spot, a quick dab with some flux and an iron may well sort things out. This is a very common failure mode for electronic things subject to vibration. Nothing to lose at all. Quote Link to comment Share on other sites More sharing options...
richrips Posted November 10, 2015 Author Share Posted November 10, 2015 Good point. I have no idea what class d stuff does when it breaks. No smoke or smell and not particularly hot. The fan still kicks in on startup so it appears the cooling is working, and wasn't running when the amp failed, leading me to believe that the amp didn't overheat. I need a new soldering iron anyway (fellow microsynth users will appreciate) so it's something I'll look into. Frankly the amp has been brilliant for clean power since I got it so a repair would leave me well chuffed and not out of pocket. I'm wondering if I could connect the non-functioning speaker-out in the LG to the other working speaker-out in a way to put both cabs in parallel to = 4 ohm?

Chienmortbb Posted November 22, 2015 Share Posted November 22, 2015 If the LG is like the Superfly it has two totally separate amps powered by the same power supply. Each amp is 4 ohm capable so running the 2 cabs in parallel from one amp. The Superfly uses an amp/power module from Alto but I suspect a compete module would be difficult to get. If one amp is blown but the other is OK, it may be easy to fault find However many class D amps may be small enough to be retrofitted into the LG if needed.
