There is no performance difference between any 6L6 in that circuit.
Some Chinese are good, my sons have had excellent reliability with Ruby
brand in their guitar amps; the older boy is a pro.
Since USA 6146's are readily available at fair prices Id stick with them.
Dont use the B version unless the manual says its OK.

Subject: [AMRadio] Replacement Tubes
Some misc. tube questions..
Can 6L6GC be substituted for 6L6GB?
Are Chinese tubes worth the cost savings they generally bring? I need
to replace a pair of 6L6GB's and a 6146B.
Thanks
