Hi everyone... I would like to hear about those of you who already replaced their tubes in a C-J Premier 10. I also find out that C-J have changed their configuration for replacement tubes from G-E to a combination of 2- Sylvania and 2- General Electric (if I am not mistakind) and would like to learn about your best experience. I am looking for sweetness and very detailed. I have already tried some Tung-Sol, (pseudo) Mullard and the old set of G-E when I bought the preamp.
You can buy tubes direct from CJ, but I buy Ram Labs tubes off Audio Advisor. I have a PV12 pre-amp. Not sure if they carry what you are looking for, but their mail order service for small parts is fast.
