Class D kits for bass guitar amp??

[chicago_mike]

Are there any good diy class d kits that would work as a power amp for a bass guitar amplifier?

I need at least 300 clean watts into an 8 ohm load.

I'd say a UcD 700 module combined with appropriate PSU and preamp.

hi mike
i'm a german bassplayer, who wanted to build a good, loud and cheap power amp for my cabinets.
i took a 300w toroid (used25$) a psu with 40.000 f condensers and philips rectifier ultrafast diodes (50$) and a ucd 400 modul (app. 170$) .
it took 3 hours to put it all together and i must say i'm very satisfied :
loud and clear, no hum, no noise, no heat , very reliable and so very recommandable !
my setup:
a hughes&kettner tube preamp, a cabinet with a 15" ev and a cabinet same size with 4 X 8" eminence incl the build-in ucd-amp.
fender precision, r&b.
so try this out and you'll be happy, i'm shure !
best regards from germany

This one from classdaudio does look good fore bassguitar
1. High power
2. Easy to bridge and 2ohm stable makes it good to bridge
3. Simple supply needed
4. Optional RCA and balanced input
5. Heatsink mounted and optional output with 2speed fan control
And you can build it to also be used in your home setup
I consider to build my bass speakers so that they can be used at home as well
With digital dsp it might even be good
But becomes more expencive
But with the huge advantage of being able to plug a guitar directly into your "stereo"

Hi,all
maybe there is something really new .... unfortunately little bee who must finish the Frankfurt Book Fair to have it.
for bass guitar I think is very appropriate, this includes an innovative, dynamic control of the signal in real time, or ALC, without it we could not exploit the full power with guitar bass.

Such an "innovative dynamic signal control" does not usually belong ino the power amp ! Maybe except it is just active in case of severe clipping.
Dynamic control belongs before the power amp and there must be facilities to influence it by the user.

Me personally I don't like compression at all I use just a hint of limiting in order to not have to use huge peakt powers. But I very much dislike the artificial pseudo sustain gained by the heavy use of compression. A decent instrument, the right strings and playing technique gives also enugh sustaiiiiiiiiin.

Apart form that the module looks very interesting - especially for a beefy bass combo. Unfortunately no one can tell from the website whether it is obtainable at all and at what price.
