先日、COUNTERPOINT SA-5000 が無事に届きました。当方、COUNTERPOINTのプリアンプははじめての所有なので、教えていただだきたいことがあります。今付いている真空管で”６９２２EH”はどこのメーカーかわかったのですが、”１２AX７”と”EZ81”はどこのメーカーなのでしょうか？またこの２つは純正ですか？教えていただけますと幸いです。ご連絡お待ちしております。
I received a COUNTERPOINT SA-5000 on the other day. I have a question or two as this is my first time having a preamp of COUNTERPOINT. Of all the radio valves that are currently attached to it, I know the manufacturer of "6922EH", but will you tell me the names of manufacturers of ”12AX7” and ”EZ81”? Also, are these genuine? It would be very much appreciated if you could advise me of the above. I am looking forward to receiving your reply.
