I need some help with my '60 99j. I decided to do a full tube swap (almost) since it had a mixed lot of tubes in it. I got EH12AX7s and Sovtek 6L6WXT+s. I haven't changed the rectifier, yet, although I have a JJ GZ34 of unknown usage waiting in the wings.
After installing the new tubes, and letting it warm up for a couple of minutes, I kicked the standby on. I immediately get a mishmash of static and hiss that ebbs and flows. But, the guitar also gives nice rich sounds at an expected volume.
So, what did I do wrong? (This is my first tube change.)
Are the 6L6WXTs not compatible, since the original specs call for 6L6GCs? Here's the write up from the Tube Depot, which is why I got them:
Any help? (missing the good Cap'n now )
What's my next step, before I blindly try swapping things?

Modeled after the vintage RCA 6L6GC "Blackplate" the Sovtek 6L6WXT+ features larger plate dimensions and improved grid structure for increased power handling capabilities. The 6L6WXT+ also features mica spacers with metal springs to eliminate tube rattle and microphonics. The Sovtek 6L6WXT+ yields a 20% higher output than the Sovtek 5881WXT and offers superior tone and overall performance.
