Ok, fair enough. I've used the 2SJ162/2SK1058 devices as replacements for the old Hitachi devices, like K135/J50 and they've been fine. Very stable, etc. The idea is obviously to make sure that there are enough devices to share the load - and decent cooling. That will keep everything within it's SOA. The cheap amps you see around these days are cheap because the skimp on the O/P devices and invariably go pop. |

Yep, 2 x 1500 into 4r for the STR 3000, although the one I had never sounded as gutsy on bass as the C Audio XR3801's I had which were rated at 1200w per channel, to be fair, the C Audios were 1U bigger than the Matrix so had the room for a much larger power supply. :)

The "Double Die" devices :) ... very hard to find originals now. On the plus side, they do seem to keep going. When we do occasionally get one in for repair, it tends to be just a single device that has gone pop, and my repair guy still has a box of ones harvested from other deceased units.

Thanks to everyone for taking the time to respond. Lots of useful information.
Unfortunately the amp does seem to have a fault on one channel. It dosen't seem to be any quieter than the other but has noticeable distortion. Any way it is now listed on ebay if anyone is interested in buying as is or can recommend someone close to Northampton to have a look for me. |
