Thanks to everyone on this site.

I just wanted to thank every one who has ever posted information on this site.  I have a late '69, early 70s 2000s head.  After reading all the post on this site, I gathered all the information I needed to get it running again after 20 years!
     It sounds awesome!  Now if I could only find the matching speaker cabnet!  Thanks again!

In general, Sunn cabinets are much more rare than the heads. 2000S ans 200S caninets, along with the guitar cabinets of that vintage, are quite rare. Not unheard of, though. Keep looking, and one will come up. Then, you'll have to decide how bad you want it!
