Hi
I've just scored a mint Fryette 2:90:2 with JJ kt88 in it
(I already own one and wanted a backup for shows)
I've just noticed a weird hum noise problem when I switch both channel A and B on at the same time
If I only play through channel A or channel B alone (other one in standby) , there's no noise at all.
I'm not sure if it's a tube problem or something worst
Here's a video of the problem
