Bass Poweramp.. What type should I choose?

[XXLPeanut]

Hello.
Im recently new to the forums.. Signed up a month ago and has been working on a preamp for my new bass equipment since.
Im doing a version of the albert kreuzer preamp, with a few minor changes.
My next project will be a poweramp for the setup. So heres my question. What type should I choose? I'm down to 3 possibilities.

1. Is using 2 gainclones hooked up as a monoamp. Each putting out 68W and peaks at 120W. Est. price $175 + transformer.

2. Going for a class-D design. I have only minor knowledge on this area , but a friend who is willing to help me.

3. A traditional bass amplifierdesign. No tube design for now.

Im playing on an active musicman s.u.b. bass if anyone think this makes a difference.

Thanks for a great forum.

Hi,

forget about the gainclones, they will expire too readily.

A more standard design with an overengineered number of output devices,
heatsinking and power supply is the only reliable way of doing the job.

Class D I'm not sure about, certainly it will be the way in the future.

Some form of limiting and compression should be included, either
in the feedback loop or careful control of the input, to avoid hard
clipping, which sounds terrible with most transistor power amps.

You might try looking at the Behringer BX1200, a 120W 12 inch speaker combo, I bought my daughter one, we're VERY pleased with it - and the price is reasonable as well.
