Thanks. I have three 5694. One has the etching on the side and is dated 1954, week 24. However, the other two have the etching on top, but no date codes. Based on yours, I am inclined to believe that these two were manufactured sometime after 1954.

Were all of them made by Raytheon? I wonder why they went out of fashion? The similar 6N7, so many more examples out there...

I would also say the 5694 sounds different from it's 6N7 cousin. It is more refined, in many ways.

A neat amp I am packing up today.
Other then EL3N it also takes 6J5 driver and EL34 , KT66 , KT77 , 6L6 for output no adapter needed.

Beautiful, I'm sure whomever is receiving this amp will sure be a happy camper!

Well, I have used that gorgeous new amp as inspiration to roll in these EL3Ns that arrived the other day. I had been so much enjoying the EL32 + (6 or 12)(J or C)5 combos that I was reluctant to change.

I am letting them warm up for a while before a first listen.



Thanks @Monsterzero for the adapters, this is their maiden voyage.

Happy listening all.

Yes, only Raytheon manufactured the 5694. As it is essentially a 6N7 with separate cathodes, it is most directly comparable to Mullard's ECC32. But while the ECC32 has the same pin-out as the 6SN7, and many other octal double triodes, there was no demand for the 5694 due to Raytheon's decision to use a non-standard pin-out, and it was a failure in the marketplace.

Yes I often run EL3N via adapters in the C3g sockets. And they are one of my favorite drivers.

@gibosi - thanks for the inspiration to get some of these. After seeing Glenn's new amp post today, I am enjoying these EL3Ns so far. They are only a few hours in, but they have nice bass and warmth without drowning out the uppers/ details elsewhere. I bet the EL3N amps with them as ins&outs are lovely too.

On another note, are 6AS7Gs really just shoulder-type versions of 6080s or are they otherwise different? I think I recall someone saying the 6AS7Gs may run cooler than the 6080s? I have a small quiet fan that I have to keep going to keep the temperature down with the Bendix 6080s.

Whoah, congrats to the person who will enjoy this beauty. With that much variation of tubes, I think I can guess who that'll be What's the left knob for by the way?

Outstanding! Really looking forward to hearing reports on all the possible tube rolls with this one.
Beautiful work @2359glenn.

Great tube, love the EL3Ns, definitely one of the top tier tubes.
Gotta love the GOTL having the capability to use all of these great tubes.

Electrically, the 6080 and 6AS7G are essentially the same tube. The 6080 was engineered to be more rugged and shock resistant for use in industrial and military applications. The result is a more compact bottle with a metal-wrapped base which does tend to run somewhat hotter in our amps. But Glenn designed his OTL to easily handle four 6080s or two 6336, and as long as there is adequate air flow around the amp, the extra heat isn't a problem.

So my advice is not to worry about which tubes run hotter and choose output tubes for their sonic characteristics. And by the way, the Bendix 6080's are among my favorites.

@Zachik is going to be very happy, looks great! The EL3N are very sharp tubes, look good on blue.

 

[L0rdGwyn]

Going way back, did anyone ever get around to trying the GEC A2293 in the GOTL? If I recall correctly, @Deyan was supposed to be building a crazy adapter for someone to give them a shot, 6 tubes per channel!
