Because of valve ring-ins in my 11-7 I made up this table to help work it out. So decided it might as well be posted.

Kriesler 11-7 valve lineups, from Kriesler Technical Service Instructions and Kriesler Amendments from
https://vintage-radio.com.au/home.asp?f=2&th=467#4129, Post 3.

The data is only meant to reflect the valve lineup changes to help with model identification. There are many other changes.

11-7, ECH35, 6U76, 6B6G, 6V6GT, 6X5

11-7A ECH35, 6U76, 6B6G, 6V6GT, 6X5

11-7B, 6J8, 6U76, 6B6G, 6V6GT, 6X5

11-7C, 6J8, 6U76, 6SQ7GT, 6V6GT, 6X5

11-7D, ECH35, 6U76, 6SQ7GT, 6V6GT, 6X5

Kriesler 11-7 Issue 2

Issue 2, ECH35, 6SK7GT, 6SQ7GT, EL33A, 6X5 (model no. 11-7E is not mentioned, but no reason for it to be dropped like I and O)

11-7F, ECH35, 6SK7GT, 6SQ7GT, EL33A, 6X5

11-7G, 6AN7*, 6SK7GT, 6SQ7GT, 6M5, 6X5 (paperwork says 6AN7 replaces ECH33 in Issue 2, which is ECH35)

11-7H, 6AN7, 6SK7GT, 6SQ7GT, 6M5, 6X5

11-7J, 6AN7, 6SK7GT, 6SQ7GT, EL33, 6X5

11-7K, ECH33, 6SK7GT, 6SQ7GT, 6M5, 6X5

11-7L, ECH33, 6SK7GT, 6SQ7GT, EL33, 6X5

Kriesler Amendments, Kriesler 11-7

11-7M, 6SA7, 6SK7GT, 6SQ7GT, EL33, 6X5

11-7N, 6SA7, 6SK7GT, 6SQ7GT, EL33, EZ82

11-7P, 6SA7, 6SK7GT, 6SQ7GT, 6M5, 6X5

11-7Q, 6SA7, 6SK7GT, 6SQ7GT, 6M5, EZ82

11-7R, 6SA7, 6SK7GT, 6BD7, 6M5, EZ82

11-7S, 6SA7, 6SK7GT, 6BD7, EL33, 6X5

Thanks for that Redxm.
Did I miss something in my reference, or is this a different reference?

Just goes to show in the pressure of business they didn't document everything.

There is an article in HRSA Radio Waves Jan 2011 which is said to be an on 11-7E with valve lineup

ECH35, 6SK7GT, 6SQ7GT, EL33A, 6X5GT

which differs from Post #2.

But the circuit diagram is not given so how it was known to be an 11-7E is uncertain as I have been unable to find the model number anywhere on my 11-7. Unknown factory change or unknown in-service change? Who knows, but shows nothing can be taken for granted.

(Some bits removed from here to Post 12 of " Kriesler 11-7 with ring-in valves" thread to remove confusion.)

I believe we have two threads on this: That only causes confusion. I have the "Kriesler Technical Manual", that, as far as I am concerned is the ultimate reference.

I started the second thread to have "Kriesler 11-7" and "lineup" in the heading, and to be a reference separate from my particular ring-in valves thread. Sorry for the confusion.

Have fixed this by moving bits around between the two posts.
