PASS F5 Clone-Question

[CVSO915]

I have a Pass F5 clone that I really like a lot. I do have a question about it. My amp has a slight , but discernable humming sound when it is turned on. It is almost like a transformer hum. It is not audible through the speakers. Is this normal or an indication that something is wrong with this amp?

Nothing to worry about but noise.
It's the transformer.
Not rare.

yes. the sound you are hearing is the transformer windings that is vibrating.
thats not un common. has it always been this way? or has it started to hum now?

I haven't had it very long. I bought it used. It does sound fantastic with my tube preamp though. I am currently looking for some HE speakers for it as well.
