A good rectifier tube should last a very long time, and seeing that the current one you have is not very old at all, chances are a new one of the same model and brand (Ray tubes Select 5U4G) will be equally as strong.
Importance of matching 5U4G rectifier tubes.
I have a Woo Audio WA6-SE headphone amp that uses 1 5u4g rectifier tube. I had just purchased a single Ray Select 5U4G tube. I was fortunate to be able to upgrade to a Woo Audio WA5-LE headphone amp which uses 2 5U4G rectifier tubes. I want to purchase another Ray Select 5U4G tube to have 2 for the new amp. However they won’t be matched. How important is it to have matching rectifier tubes?

@noromance +1 You are correct! |
I don’t know about matching rectifiers, I’ve never had more than a single one is any unit I owned or heard, but I’ll share this: my friend had Kara make him a preamp http://www.dehavillandhifi.com/UltraVerve-Preamplifier.htm She included new tubes, and some alternate used tubes, including a Rectifier. We listened here, heard subtle changes, then we were both quite surprised by how much the sound changed with the alternate rectifier. I had no idea, both tested ok on both my tube testers. |
Congratulations on getting the WA5. I have one as well. This was the most significant upgrade of my headphone system of all time. Literally jaw dropping (after upgrading the 300B tubes). First the rectifier tubes are not as important to sound. But might be important to the longevity of the tubes. I would send it in to Ray and ask to buy a matched tube. Also, I HIGHLY recommend Takatsuki 300B tubes for that headphone amp. I know they are expensive... but worth every penny... And their typical life is in tens of thousands of hours, These tubes are unreal... especially in this amp. You can see my headphone system under my userID. |
