RIGHT below these are the 25DC57 and 25CC5. They do NOT have the VRT--instead series pass regulation. Otherwise--they are just like the 25DC56 set.

IIRC the other change was audio. The C lines had the same audio

Changed to an upright card style pcb ( 9-???). And maybe some day we will
find the truth on the mysterious B line chassis......
