RCA part?
 

Chassis # ITC008FHM Model # 27R411T:
Loc # TL035 S2055N what can you replace
it with? Also, what do replace the S2000N with
in other RCA sets? I don't mean NTE, I mean like
2SD2578, etc. Rono.

crossing S2055 to NTE2302 the using

to cross back comes up with subs

S2055N is exactly the same as a S2000N except the 2055 has an internal
damper diode. A BU508DF is a good sub.
