I am searching for a 20 kHz to 10 MHz range power amplifier for driving a saline solution load. Ideally, I want something I can just plug in. But my budget is <$4000. So my options are limited. Any suggestions?
Second-hand or private sellers are also fine. Thanks!

 

Welcome to AAC.

Your budget may be a problem. But you didn’t say how much power you need, which is certainly material.

The ENI 240L seems to be the best option, but the lowest price I can find is about a third more than your budget. If you don’t need the 40W, it might be possible to do something with a brick type amplifier, but it might require searching a bit to find something. A company like Pasternak might have something, or maybe Minicircuits, but I didn’t check.

Also, constantly check eBay, it can be a very good place for things like this.

 

Thanks, Ya'akov.
Yes, the power is an issue. I prefer at least 40 W rated power.
The lowest I can go is probably 10 W. But by 10 W, I mean 10 actually delivered to the load. I have the same setup for the audio frequency range and the audio amplifier managed only a fraction of the rated power.

Wish I could help more. The 240L seems ideal other than the cost, but budgets are budgets. At my university it was common for research groups to buy equipment on eBay to save money, so that might be fruitful eventually

 

I'll watch out on eBay and the like
