firebox pc board

[willis]

mr Jack, i fried the leds on the firebox flicker board on the 120.5 logging loco.
i contacted parts to order, 2 different pages that came with the loco on page #G828x-IS006 shows part#G811x#PCBO3a, the other page  G828x-IS007 shows part#G811x#PCB01.
the lady in parts is telling me that the pcbo3a is in the gearbox ass. and that the #PCBO1 which is the same # as the main board?  this is a pc board with 4 wires that plugs into the main board.
when you look up the main board, all it comes with is the main board and the PCBO4.
the lady was very nice, but trying to get her to understand what i was trying get across to her, and her not knowing why there is 2 part numbers for the same board on the 2 different pages.
to keep from loosing my cool, i just hung up and will try to get help here, HOPEFULLY.
thanks, willis.

Dear Willis,
Call back and ask for Irv, the large scale expert. He'll understand.
Have fun!

hi all ,    i guess old age eyes cannot tell that the 8s after the G in the part numbers are Bs .
after much back and forth, Irvin(sp) and i figured out what i wanted.
thanks Irvin, hope you can find the board.
