Chameleon 2000d's running bass?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi all,
         Just looking for some advice! I have 2 chameleon 2000d amps, that i am going to clean up service and repair. I plan to bridge both into 4 ohms to run two stacks of 2 x fane collosus 15xb bass bins(plans on the fane website). I was wondering if people had any opinions on these amps for bass applications?
cheers
kieran

	One mod I've done to our 2000D is make the fan run at full speed all the time. True, its a bit noisy but the rig drowns that out! Inside ours was a transistor glued to the base of the chassis, I just removed that and linked the fans up to the low voltage supply. The Transistor is used to limit the current, and so limit fan speed. btw, could you take a look at what fuse you have fitted at the back, near the mains socket. Cheers!

	Will do, been busy recently, i'll look at the amp fuse over the next day or so, what do your think about the cab/amp plan in general, do reckon the chameleons will handle it?

	I used to run the 2000 and 3000 and I think 3600's. Only ever run the 2000d on mids and if you went really silly with the voulme it was possible to blow some output transistors. The same was also true of the bigger amps too. The main problem I had was with all the internal wiring. I had some early ones and all the cabling was on samll plastic edge type connectors. All the amps I ran in installs were fine, but when you started moving them around some would stop working. In the end I had to solder all the internal wiring to the PCB. This stoped the probelm. I think the later ones used better connectors as when I talked with Malcom he was aware of the connectors coming lose inside. They are not to bad an amp if you don't go mad. I never bridged any of mine so I can't say if it will work. They do get very hot as Mykey said, and I only used to run mine into 4 ohms per side. I think 2 ohms might be pusing it a bit unless you have some really good airflow going on around the amps.

	Ahhh, i think i may have done this with one of them, which is why it will need repair.. Ah well you live and learn, lyndon i'll get the fuse rating for you, but it looks like i'll have to save up for 1 or 2 decent amps to run the subs. It does'nt look like the chameleons will handle it! I've been looking at the t.amp proline amps, what do you guys reckon to them.

	The internal wiring, as Rog said is pretty rubbish. My problem is not so much the connectors themselves, as on mine they had blobs of hot glue to keep them on. More the problem is the boards aren't secured very well, and so tend to move about, the chassis isn't one piece either. On one of our 2000D, a PCB was so close to a main supply capacitor the solder joints rubbed over the outer plastic coating and shorted. A few diodes replaced here and there, and a burnt track and its OK again. I've made sure I put them back together better than they came out the factory. As Rog also says, I think it might be best to stay away from 2ohm loads, they just don't seem to have enough output transistors. And, being a Bipolar amp, watch out, otherwise you can say hello to thermal runaway!

	can anyone get the wiring diagram for the 1600d as i brought one the other day for pennys and it needs a good look over before i turn it on, and ye also a bit rubbish construction, in mine the glued down transformer had come away knocked the inside around a bit,

	The amps both have different fuses fitted: T12,5a/250V and T16A250V.

	12.5A and 16A ?!!!!! Blimey I bought ours in non working condition, and there were no fuses fitted so I guessed around T10A. What happened was one of the amps had suffered over heating, because the fans stopped working and the output transistors shorted internally. As there was no DC secondary side fuses to blow, the mains fuse had to blow. For some reason the mains fuse decided to melt the IEC/kettle inlet into a huge mess... never seen anything like it before! I assumed this was because the transformers primary side couldn't quite pull 10A, or maybe it was a bade fuse holder/fuse? Also, the IEC inlets are rated for 10A, so having a 16A fuse is a bit dodgy, bearing in mind to blow a 16A Timedelay fuse takes quite a bit more for instant blow.

	Must admit, it did'nt seem right when i found that out today. Amps where sold to me by pa company as fully serviced by an ex hill engineer, seems they probably were'nt. What fuses would you recommend? This might be why one of my amps failed on me, the fan seemed to stop working, and it would play for a while and then overheat then shut down. Where are you based and would you consider doing a overhaul job on them, you seem to have a lot of experience with this particular amp.
