Best Regards,
@Elliot, do you have internal pics of the MX3000a and MPX1200/MPA1100? Just to see if there are any layout changes.Cheers to all who have contirbuted so far. Clap


The Schematic of the EX 4000 labels the MPX 1200 (JBL) on the same overlay sheet.

The MX 3000a Schematic is exactly the same as the EX 4000.

The EX 4000 came first followed by the JBL MPX 1200 then the MX 3000a. All three are exactly the same from a power persepective.

Best Regards,
Elliot Thompson

Exactly what I thought, but only has 8x smoothing caps though.

Big boys have at least 12x. Yes Caps can have different values, but from upgrade point of view 12x upgrade caps, would be better than 8x.

What bothers me more is the lack of output transistors - only 8 per channel! Seems not too many for claimed 1200 W/ch @ 4 ohms... The smallest sibling, TA-450, which I happen to have, has 4 transistors per channel (and four 10000 uF caps), and is quoted as 200 W/ch @ 4 ohms. Unfortunately, I don't have a camera, so no pics, but it is very similar to TA-2400 internally - just smaller transformer and heatsinks, less caps and transistors.

As for TA-2400, a guy on a local forum said that they are prone to blow output transistors if pushed hard @ 4 ohms. Fortunately, these transistors are cheap. Also, this same guy said that he has done some modifications to the amp, increasing reliability.

I would think there would be a similar compliment of them on the other side of the heatsinks.

Don't criticize your own competition, it looks like a publicity of your own commercial products.
