When I owned tube equipment, I had a preamp with 12AU7 tubes. Certain brands would flash brightly when powered on. I checked with two tube vendors who assured me that the flash was nothing to worry about -- that it was a characteristic of some brands and not others. So perhaps the same is true for the tubes in your Onix.
Onix SP3
Hi,
Can somebody please tell me why when I turn my amp on the rear tubes (small ones) on either side go really bright for a millisecond and then dimmer down? It plays and sounds fine, the bias is set correctly. It has been doing this since I bought it. It has had minimum use, maybe 50 hours (if that).
Anyone got any ideas please?
