Aguilar TH500 fan operation

Hi everyone. I've just acquired a pre owned TH500 and I'm just enquiring if anyone knows how the onboard fan operates

 

When I switch the amp on the fan does not operate. I've not played it properly yet and it may come on after a period of time

 

Does this appear to be the correct way it would run or would it come on when switched on and stay on?

 

Thanks

Mike

Download the manual. It may have a thermal switch.

C. Protection Features The Tone Hammer 500 is equipped with several protection circuits designed to prevent any damage to the amplifier in cases where the limits of the normal operating range are breached. Protections include an over current, an over temperature, DC, and HF detectors. If any of these circuits are triggered, the amplifier will either limit its output power, or shut down. In case of a shut down the amplifier will rapidly try to restart, checking if the faulty condition is still present. In case of shut down, both Operate and Status lights will turn off.

Mike, the 500 fan will activate after the amp has been driven a bit. Light noodling will not make it activate'. Hope this is clear enough?

Thanks Snorkie that makes sense and is really helpful :)
