Sylvania 6CL6 Tube

Sylvania 6CL6 Tube  Interchanges with 6197, 6CL6, 6AG7, 6AK7, CV5041, and 6677. 

This tube has been tested on a Triplett tester for emissions, leaks, shorts, etc. and tested good.   

I am listing this tube as used, though it may actually be new.  This is from a huge batch of tubes that were mostly new, but some had been put into white boxes because their original boxes had lost their rigidity.  So expect a used tube, and if it turns out to be new, it's a bonus for you.
