UA 175B Limiting Amplifier - Transformers Identification

Hi,

I'm trying to identify the UTC transformers used in the Universal Audio 175B.
So far I've come across this references but can't find more info on the T3 UTC PA-6003, anyone can help ?

T1 : UTC 0-1 : Low Z to grid (Pri : 50, 200/250, 500/600 Ohms // Sec : 50 KOhms)
T2 : UTC A-19 : Plate to PP grids (Pri : 15 kOhms // Sec : 80 kOhms (split) )
T3 : UTC PA-6003 : ( Custom winded by UTC for UA's 17(5/6/7) Limiting Amps ? )

Thanks for your help !


PS: I'm looking at UTC 1963 catalog
