Default Nos 6h30

Hi,

Will NOS 6H30 tubes make a big improvement over factory tubes ? Need some advice thanks.

Regards,
Joe Ling

6H30-DR - people who paid a lot of money for them will probably say they make a big difference.

I found their sonic effect very much dependent on the gear they are used in. Eg, CJ, negligble; ARC, minor, a bit more extended highs.

I tried them in my ARC. Not only did I find the difference very modest, they are so hard to find and if you find them likely counterfeit or previously used so maybe weak. Even if you have none of those problems the stock is so small you will not be able to get ones with matches triodes or that match another well. So the real question is better to get new, strong, even croyed ones with matched triodes (GM) or 6h30dr that are unmatched and have unknown usage? For myself I decided the former.

Parts Connexion selling matched pairs at a premium price. I need 2 pairs for my ref2 phono which adds up to a pretty penny. Thanks for the reality check.

I used the 6H30-DRs in an ARC Ref 2 Phono and in the 2SE. Nice units. Those tubes do last a long time. And they did have a greater impact (though minor) in the Phono stage than in the Ref 5SE linestage. However, imo you'll get better value for your dollar with a decent isolation platform.
