Noisy 250 watt amp used with TN 1225 sub

I've been very pleased with my TN 1225 sub for many years but it appears that the HSU amp used with it is now failing. While it still appears to produce the bass, there is a kind of static like noise superimposed over it. I substituted another powered sub I owned and there was no noise so it's not coming from the receiver. I also hooked up a different speaker to the amp and the noise persisted so it doesn't seem like the sub driver itself is to blame. I did not see any obvious problems with failing caps inside the amp. So I'm wondering if there is an acceptable replacement amp that I could substitute. Is anyone familiar with the 250 watt Dayton Audio amp that looks like it might work?

I could just bite the bullet and get a newer box sub but I like the small footprint of the cylinder and I hate to just junk it or sell it on ebay.

Just an FYI, I got the Dayton amp and it works well with the TN 1225 sub.
