Alan,
that is very interesting. I am glad you told me that. I thought that tubes clipped "softly" and would not damage tweeters. I know of the collapse you mentioned because I do drive a pair of 89db speakers with the SET.

I know it won't drive the 80's to be really loud and I am just curious to hear how it good it sounds.

Thank you for everyone for the stereo input and the mother jokes.
