EA iamp 200

Hi,
I have an older iamp200 (black faceplate) that is a fantastic amp, plenty of juice for anything I've ever needed it for up until recently. So, as much as I hate to, I'd like to trade it up plus cash for any EA amp with more power. It's pushing an Acme B-1 but it doesn't really have the power to push it right so the speaker farts sometimes.
If anyone is interested. I'll get pics up by tomorrow.
Thanx
