Thanks a lot Mattmiller. Your realistic explanation was awesome. I did remove it exactly same way you described. I tried with my telefunken tubes but still don't like phono section. I will try GL or mullards. Thanks again.
Tube rolling for C 220
Hello, I want to try to use different tubes for my Macintosh C 220. I unscrewed but still cannot open the case. Can anyone let me know how to open the case ? And I would appreciate if you could share your experience with tube rolling for C 220. Thanks.
