274B Rectifier and Rachael
10/05/24 at 12:02:58

Hi there... I am relatively new to tube rolling with my Rachael. I've rolled the input and output tubes without incident and recently bought a Sophia 274B Aqua II rectifier. I noticed that the pin configuration is different than the Decware branded rectifier that I have. Do I need an adapter to use the 274B? Just wanted to check. Thanks!

You will likely need a socket adapter to use the Sophia 274B in place of the standard rectifier. These adapters are relatively easy to find online, especially from places that specialize in high-end audio tubes or components. They’re typically designed to allow you to use a tube with a different base type in a socket that doesn't natively fit it.

Make sure to get one that’s compatible with the 5AR4/GZ34 socket for your Rachael and the 5-pin configuration of the 274B. Once you have that, the tube should work fine, and you can start enjoying the benefits of the Sophia 274B!
