SE84UFO2.1 Power Transformer Hot
04/16/23 at 00:47:15
 
Anyone know the operating temperature of UFO2.1 Power Transformer? I have (2) UFO2.1ís and with one amp the Power Transformer is cool/cold after hours of operation. On my other amp is is warm/hot. Same environment. The cooler transformer is an earlier SN and appears to have a different transformer without casing edges. May be same spec but different casing. Any thoughts appreciated.

My 2.1 has always been very warm, received fall 22. Sorry do not have any other Decware amps to compare to. This is completely expected to me though.

My only thought is maybe the tubes on the older one are weak. You can try swapping the tubes on the two amps and see if that changes anything. Other than that my advice would be to email Steve if you suspect a problem.
