Tone Hammer 500 Sound Thinning Out

I purchased an Aguilar Tone Hammer 500 about a month ago. Along with my two GS-112 speaker cabinets,
the tone is incredible.

However, last week at band rehearsal, I noticed my sound was starting to thin out and the speakers were losing power -- the bottom end (bass) was disappearing.

After I got home, I started trouble-shooting by switching guitars, cables, speakers, etc.
What I eventually noticed was that the cooling fan was never kicking-in.

I noticed it because shortly after I received the unit, I remarked to myself how frequently the cooling fan ran.
Now it doesn't run at all.

Am I correct to assume that since to fan is no longer working that the protection circuits within the amplifier are kicking-in and are limiting (choking-off) the power delivered to the speakers?

Note: I don’t think I’ve blown anything because I’ve never had the Master control above 4 or 5.

I’m going to have the TH500 replaced but I was wondering if a solid-state amplifier guru could validate my finding.

Thanks and best regards.

Sorry to hear something's not right. The amp doesn't limit or choke off volume as it gets hot. If it passes the thermal threshold, the thermal sensors just shut the amp off. And that won't happen unless the amp is broken.
I don't know what's going on with your rig but if you contact us at [email protected], we'll figure it out.
