The GE probably had a 10BP4 originally, I believe the FP4 was introduced later as an upgrade but I may be wrong about that.

It says it's a 10FP4 on the tube list , but perhaps it was a later set and they used the 10FP4 in favour of the BP4 .
I dont see any ion trap in the pictures of it , It should be here this week ,I'll know more then .
Whats in the 10T1 Locomotive ? Apperently , it's much the same .

My GE 810 originally had a 10FP4 but the neck was broke off when I got it. A 10BP4 will sub except it will require an ion trap. On most sets this is not a problem but on some of the GEs (including the 810) there is little room for the trap due to the placement of the electrolytics.

I have the 10T1, which I think was the lower end model. Its tube list says 10BP4. Someone in the past upgraded to the 10FP4. It has a great bright picture, with lots of contrast.
