A48AAB13X02 Tube drop in for K4600?

Send the original tube number and the verified replacement tube number to Tubular and post it here as well. Very handy.

If you know where the replacement tube came from (e.g., RCA model 210) that would help too!
 
Excellent! Sounds like you found a winner then.

Congrats on the sucessful tube swap!
I did this as an experiment expecting it not to work. Lets see how bad it looks and hope the deflection board doesn't blow. I expected all sorts of geometry, bowing, warping, and purity issues. Nope. Looks great.
 
I found another one of these TVs and did some more comparisons.

K4600 yoke / TV yoke

2.5 / 3.5 ohms
8.2 / 11.8 ohms

2.0 / 3.03 mh
