ReekBlefs-
:)
This is all three of my TE amps.
Can't really see the top one, it's a V-type valve preamp (apparently modelled on the Alembic F1X) into a TE PPA300, which is a 2x150w power amp. It's the one I gig the most, as it's significantly lighter than the other two :)
Edit: If anyone's got a Class D power amp going spare, ideally 2x 4ohm or 2ohm minimum, I'd be keep to buy it. Or any recommendations?
Oh, and I've also got a Warwick Rockbag 3U wooden rack thing (fabric covered) with a knackered zip on one of the end flaps, free if anyone wants it and can get to New Cross to collect it.

Just dug out the relevant email from Ken, here's the excerpt, I was off by a few watts :)
Finally, I've just hooked the amp up to my signal generator and oscilloscope, to check that she's throwing the right shapes and to measure what kind of power she's able to put out. The shapes are good - nothing ugly or horribly unbalanced and no sign of parasitic oscillation - and the figures tot up as follows:
VA350 working into a 4 Ohm dummy load.
1kHz Sine wave injected into the Line Input and the signal generator's amplitude increased until the VA350 reaches the threshold of clipping.
At this point, the RMS AC Voltage at speaker output was measured as 39.6
Power calculation goes as follows:
39.6 squared = 1568.16
1568.16 divided by the 4 Ohms of the dummy load = 392.04 Watts
Loud enough for you? ;-)
Cheers,
Ken

Cheers! The top one is an AH600SMX, 2x300w solid state power amps with valve and SS preamps.
The one below is a VA350, 6x Sovtek 6550 output valves and the option of either the 11-band preamp or the valve preamp with nothing but a volume knob. Sounds amazing :)
I got it serviced a couple of years back by a guy called Ken Cumberlidge. He's in Norfolk but I can highly recommend him. I received really interesting and well-written email updates from him through the whole process. Proper story teller, in a good way :) after replacing the tubes and a bunch of caps and other bits he tested it with all his oscilloscopes etc and found it was making 400 clean watts before it started breaking up. It's a beast!
