Title: Mullard OC2 Black glass
Post by orangecrush on 12/14/15 at 03:04:35

Anyone have these?

I just picked some up, will listen to them this week. Beautiful black glass. Shorter then most OC2's.

This sounds like a 75C1 (I think the European designation for an OC2 VR). If so, I bet you will like it. I use them, though not Mullard labelled, they are English made and sound great to me. I have another pair that looks exactly the same (black bottle shorter than OC2), also labelled 75C1, but Valvo labelled. Recently put in a Mullard labelled OC2 for a listen (the taller bottle size of RCA and Raytheon OC2), and it was really good, my old standard, but I like the 75C1 better, so back in it went.

Here is a pic.  Will, are these what yours look like?

Yes, this tube looks like an OC2 labelled 75C1 as best as I can tell. Looking forward to your impressions. I really like them.

After a week with these tubes, I will be keeping them in. Slightly warm and relaxed or sophisticated for lack of a better word. Plus they look cool!

Sounds like what they do here. Subtle in some ways, but not in others, I think your using "sophisticated" is a nice term for them. They seem to better differentiate more fine information, filling around the edges with texture and space, and this relaxes the overall feel and sense of pace a bit.

Will, you verbalize so nicely what you hear. I agree completely with your description.
