Is it save to convert XLR to RCA?

Could it be a speaker issue? I know it is passive, but.....

I can't envision a way in which a passive speaker could cause the symptoms you have described. But I guess it is conceivable that a problem involving the front end of the amp, or the interconnect cables to the preamp, could be AFFECTED differently depending on whether an electrostatic speaker or a passive dynamic speaker is being used.

Did you get your buzz solved?? Was hoping to talk about Dude some more too.

Yes, the buzz is gone and all is well!

Excellent! How's that Jensen xformer working out for you? My Dude should be shipping to me soon...I've got butterflies...I actually built a larger, beefier stand to accommodate it too....(My Dude also has the 5 @ 6sn7's and the heavy duty transformer...). Stay in touch. Best

Hey there Grannyring.... sorry if I missed it in your previous posts but how did you end up eliminating the hum?
