Tube Question is 5687 tube same as 5687WA??


Hey Ho tubeheads!

I just want to make sure that a 5687WA tube can be used to replace a 5687 tube in my SF Power 2 amp. What does the 'WA' mean anyway?

Thanks a bunch!

If your equipment was designed for the WA, the regular may not handle enough voltage. If you have the regualar and want to move up to the WA, go right ahead.
