I bought an old Amcron Macro-tech 2401 from Ebay and it has a couple of 'issues', despite a thorough hoovering.
1) a bit of a thump when you power it off (OK, I know that's not right);
2) after a while it gets hot and periodically each channel cuts out.
Admittedly I was using it to drive mid/tops, three 8ohm cabs per side, so 2.7 ohms per channel. It wasn't a particularly hot day and its in a well ventilated case with two fans. I thought Amcrons/Crowns were supposed to take this sort of abuse? Or is that just sales spiel?
I don't know if the two problems are related; I did get this advice (both from Crown) about the power off thump:
"It could be a leaky cap in the 15v supply. I would try checking C1 and C2 on the main board."
"You can try placing a .01uf 250v capacitor across the power switch terminals as a filter."
Can anyone recommend where I could get this fixed? ideally somewhere near Exeter.
Many thanks - all advice gratefully received!
