Despite my best efforts, I have been unable to coax so much as a flicker of life from this amp, yet the guy I bought it from swears it was working just fine before the courier uplifted it! Have changed the fuses and looked for any obvious signs of impact damage or anything loose, but to no avail thus far... Can anyone even suggest where to look next?
All out of ideas here.

To be honest if you have to ask you should really be dropping it in to someone more qualified, you can get quite a nasty shock poking about inside amplifiers even when not connected to the mains if you don't know what your doing (as well as causing more damage).
Is power getting to the front panel Ie does it light up at all? Edited by colint - 04 May 2011 at 4:26pm |

Never criticise another man until you've walked a mile in his shoes. Once you have, call him what you like, you're a mile away and you've got his shoes!

Ditto what Colin has just said,dont fiddle if you dont know what you are doing,it could be fatal.
Is there power going to the on-off switch? is there power coming from the on/off switch to what looks like a board just to the right of it? is there power on that board? is there power going into the transformer? is there power coming out the transformer? etc etc.You will need a tester/meter to check,or someone who knows what he is doing.

Colint & JBLman,
No and No. The front power on/off switch won't light up, and I had thought that a faulty power switch might be the most obvious fault.
I'm not poking around with the power on, and I do have a Fluke multi-meter and power testing screwdrivers to check for current, so i'm just on the right side of total idiot!
Nonetheless, I appreciate your concern, and think I will take it to someone much more experienced for appraisal/repair.
If you can understand, that I just wanted to eliminate the most basic or elementary of faults, (like blown fuses or a loose connector), before handing it over to an expert.
I have read on here, that these Ecler PAM amps are supposedly a doddle to work on for those in the know, and that they are known to be reliable workhorses. So maybe worth repairing?

These PAM1400s are easy to work on, the output modules come out on plugs. However that won't be your problem, it will be something simple. If the neon inside the green mains switch isn't on, it will be a very simple fault like blown fuse or wire off.
They are built like tanks and very reliable. Yours has obviouly done some work judging by the battle scars! I assume you've checked the obvious like the fuse & connections inside the mains plug? The mains power comes down those blue & brown cables to the front soft start board, out of that onto the mains rocker, and back in, then onto the mains toroidal. The lack of neon light on the switch speaks volumes. |

A common fault on these amps is that the mains switch burns out, check if there is mains on the incoming connections, if not is there any mains getting to the circuit board on the back of the front panel? if there is no mains on that board then you have no fuse in the plug!!

worried Current is not what you should be trying to measure at all for these basic check. This could be quite a bad thing to attempt here. Please ensure you are using the voltage range on the multimeter suitable for 240v. Follow instructions as per others. Sorry if you know how to use a MM but getting this wrong is not healthy for you or Amp or MM.

You should be able to trace the fault without plugging it in. Do check the bus caps are drained, some can stay up weeks

Many thanks for all your suggestions good people.
Looks like you were on the money Steve: there's no power beyond the on/off switch, so that at least, will need to be replaced.
Does anyone on here deal for /with Ecler parts?
Also, can anyone recommend someone in Central Scotland for a proper amp service? Think it's worth having this and another thoroughly serviced/ overhauled. (I was never trying to do someone on here out of Professional business, just wanted to investigate for myself 1st & maybe learn a little.)

Just looking at the photos,that on-off switch doesnt appear anything special,if you can remove and take a photo of it,im sure some one on here will know a stockist of a replacement.
