I have a pair of Sylvania VT 231. 6SN7GT on my OPPO 105 Modwright and when I open the drawer on the player I can hear the noise of the opening on my speakers
Are these normal??
6SN7GT VT231 TUBES
I love the old VT231 tubes!
The best sounding 6SN7GT ever...Sylvania, Raytheon, RCA, Ken Rad Etc. They may still be found, if you have $$$!! Where can I find true NOS VT231s? Any favorites that I missed?
(TS never made a VT231 - but their old black glass tubes with oval micas sound great!)
