I believe @ColSaulTigh recently rolled one. Mentioned over in the Woo Audio WA6 + WA6SE thread...in comparison to a United 596

I have the clear Sophia (same bulb except for the glass) and I'm currently A-Bing it against a USAF 596. I think the Sophia presents toastier, with much better bass and warmth. The USAF is much cleaner and does better with the high end, but lacks warmth.

Was browsing the world-wide-web late night.... I've been enjoying the Brimar 5R4GY sound signature .... thought the KB/FB was interesting so picked up another

Has anyone compared the Raytheon and the General Electronics 1641 rectifier?

 

[ColSaulTigh]

I might have a slight rectifier problem....

Recently picked up a Mullard Amperex NOS 5AR4. This is the first 5AR4 I've tried, and I was quite surprised how small they are! The seller described it as Type F32, 4 notch, with a 1963 (B3G1) date code. The graphics are very cool on this one, just like my Bugle Boy 6DJ8's I still have. My WA22 has never been dead silent, but with the new iFi GND Defender and this rectifier, it's about as quiet as it's ever been.

The GZ34/5AR4 is an outstanding tube. I run a metal base version in my studio six with fantastic results.

Here's a great reference page for the GZ34/5AR4 rectifier that does a very good job of explaining the production years and differences.

Enjoy your new 5AR4!

Is anyone running the German made Elrog 5U4G?

If so, please share your impressions.

I agree with Robert, 5AR4 is a great tube! I could be wrong...but always fun to try...I believe your tube is Philips made:

B = Blackburn
3 = 63'
G = July
1 = First week

@gibosi or others on the thread, might correct my attempt if/when they have a moment.


I have a Phillips / f31 / 1958 Sittard. Absolutely wonderful.

Philips had purchased Mullard by then, but as the tube was made in the British Blackburn factory under the Mullard name, then it is considered Mullard

I also really like tubes from the Sittard factory from the 1958 era. I have some brown base top DD getter EL34 that I really like.
