WTB: Good Used 500W Sub Plate Amp

[DIYNut42]

Looking for a good used 500W plate amp. It'll be pushing an RSS390HF in 4.5 cu ft sealed. So it doesn't need to be anything super high end, but I'd prefer that it was a reliable brand. They're cheap enough new, but I always like to feel out the used market before pulling the trigger.

I have a Dayton SPA500. It's an older version, does not have the cooling fins. I used it (gently) for 10 years w/ no issues, other than sometimes a turn-on thump. I also have a Bash 300w that I bought on impulse because it was on sale that I have never used. Not even tested it. Let me know (PM) if you are interested in either, or both.

Thanks, cooper. I may have found a NIB O-Audio Bash 500 worth the money. If that falls through for some reason though, I'll be in touch.
