Carver PM-1.5

How's it going, I'm Darrell and I'm a new Carver amp owner. I own 2 amps, the PM-1.5 which is hooked up to my Kenwood KT-5020 receiver and my Kenwood GE-7030 equalizer. My Kenwood amp bit the dust, my fault, to many ohms. I had my other Carver, a PM-2.0t hooked up first but it quit on me, now it just has a real low beep. I have to use the fuse cap for my pm-1.5, I only have the one. The thing is, I'm not sure if I should continue using it, as the fan hasn't came on, I don't blast it at all, for that reason. I heard that the pm-1.5 is a lot better than the pm-2.0t. I did kick the 2.0t up a couple of times but only to 3½ which was pretty load, I don't think the 1.5 is as loud at 3½, but I keep it at 1-1½ because of the fan. Well anyhow that's what I'm doing now, music 🎶 not tv. Got to get back to working on my moms Nitro, new brakes pads and rotors plus other repairs, just purchased when her car got to hot and blew the head gasket and possibly cracked the head. She had that auto crap which they ripped her off. Until whenever, later
