ZROCK Tube Rolling
08/06/17 at 18:38:37
 
I have about 50 hours on my ZROCK2 and it is hitting its stride with a wider and deeper soundstage (than when it was brand new (three days ago).

The tube Steve supplied is a red tip 5963 made in U.S.A. and Steve told me he found some special NOS tubes for the ZROCK.

I am curious what is the make of the tube that Steve supplied (it is a short plate gray with two long ribs and three cross ribs (like a double pane window). The "Window Pane" is flanked by two small rectangle holes aligned with the center cross rib.

Photos to follow

I have enjoyed tube rolling in the past, does anyone have any suggestions or should I just enjoy the tube Steve supplied for the 10,000 hours

My research says the 5963 U.S.A. gray plates is a RCA tube

Peter, thanks for weighing in. If you are enjoying the sound of that tube, keep using it for a while. It sounds as if it's a good one.

I'm interested in hearing more of your sonic impressions!

I agree with the following that another member posted:

The ZROCK made a very noticeable improvement in density throughout the frequency range everything sounded richer, fuller with more detail and with an unexpected increase in the soundstage which surprised me.

I am really surprised by how much more information I am hearing now and how much wider and deeper the soundstage seems to be.

I was also concerned that I would have too much bass, you know the non musical fill in type bass, not the case at all, everything is very balanced tight and full.
