I purchased some Sylvania JAN 6BQ5's and put them in my FX10. I am fairly new to tubes, but they don't look the same when the amp is running. On a couple of them I can see some red glow on the plate on one side or the other. It's fairly small. One tube had this glow was much brighter and larger.
Is that normal?
I also bought 2 Telefunkin preamp tubes (12AX7's). they look like the JJ Teslas I took out.
Also mine came upgraded with JJ tubes. The stock EH's are sitting there as back up.
