On, no signal needed, 60 hrs, burn-in is done.
I bought tubes from Brent Jesse.
Did NOT like them.
He said, ok, finish burning them in, then keep or return them. Top line were his instructions which I followed.
They did change slightly, I still did not like them. I picked another I knew I liked (I had used spares of them), half the price, full refund (I paid return shipping)
Sounded great brand new and GREATER after 40-60 hrs.
