Interesting, it looks identical to my RCA tubes, "umbrella spokes" and all.

The umbrella spokes are quite different.

Oh yeah, looking closer mine extend below the mica, but they don't loop up as high as the Phillips, and are flush with the top mica.

If someone's looking for a 596, this might be a good deal.

I really gotta stay outta this forum. Hehe
Thanks for the tip.
It’s good to have a backup.

wow thats a good deal on 596

oh and hello everyone

Here's a pair of 1641, the little brother of the 596. While the 596 is good up to 60,000 feet, the 1641 is only good up to 10,000. So if your system is located at an altitude higher than 10,000 above sea level, the 1641 would not be recommended. lol

@Dubstep Girl reviewed them in this thread. Go to page one.

To my old and worn out ears it sounds similar to the 596....

Agree with @gibosi, very good rectifier. In the Glenn OTL.
But I’ve only used the 1940s mil spec version.

In case anyone is interested, I found a pair of my beloved KR-Audio 5U4G Riccardo Kron Anniversary Edition Rectifier tubes for sale. I've bought from him before, excellent seller, but he's firm on his price.

Go get 'em!

When testing the USAF596 on an Amplitrex AT1000, do you use the 596-5U4G adapter and test as 5U4G?
