It could be the 8 N 2,5 PL 8Ohms from SICA. part-no. Z005200. they claim rated power was 250W with pink noise, test-period 2h.

Lundgaard names Sica as their supplier. Sica is an italian company. They are also the manufacturer of the Jensen speakers.

Salut everybody,

yesterday I was at a concert with Ulf Wakenius (Wes Montgomery tribute) and checked the tiny 8" amp he played: http://www.lundgaardamps.com/page6.html

It was the loudest jazz-concert I've ever been to. And now i know why:

"For bass and other power demanding instruments like a jazz guitar, choose the 550 or minimum 300 watt version."   :loco

they use IcePower class-d modules.

Hi Teemu,

thanks a lot for mentioning QuilterLabs. I didn't know those amplifiers yet. Funny enough, one won't find the term "class-d" anywhere in their product descriptions. As if that must be kept a secret.

The Quilter Tone Block is exactly what I had in mind. So if I was reasonable (I am not), I should give up the Hypex-plan ...

QuoteGuitar scene is always at least a few years behind of everything, if not few decades. ;-)

Maybe a PWM-amp with RF-Power-Tubes would be the way to go?

Regards,

michael

I bridged the QSC (I meant USA370) just to keep both channels (110W @ 8Ohms each) busy and evenly loaded. Not that I ever would need the power.

And it's great fun to startle the horn section from time to time ...

Salut everybody,

I am playing a SansAmp TRI-A.C. through an elder QSC-PA amplifier (USA 360, bridged).
To get rid of the very heavy (but very powerful and reliable) QSC I would like to use one of these modules

http://www.hypex.nl/product/ucd-amplifier-modules/ucd400hg.html

together with the recommended switchmode power supply.
Does anybody ever used an UCD400 or UCD180 as a guitar power stage?

Are there any commercial guitar-amps in class-d? Like Crate's PowerBlock with the TDA8920B? On the datasheet of the successor TDA8950 no pro-audio applicatons are recommended. Do they have reliability issues?

Greetings,

Michael
