I had purchased a LGB F7 A unit B&O with some other items. Now that our layout is nearing completion I was trying to find the B unit so I could have sound. I have been told that this was only sold as an ABA set. Is this correct?
As far as I know they only came as part of an ABA set. It shouldn't be too difficult to add a sound system to your A unit. I have the LGB ABA set and the sound is excellent, but I doubt that anyone will have an extra B unit. I have added Phoenix sound to several USA T F3s. It is a lot easier to add sound to a diesel than it is to add sound to a steamer.
The F7 A and B units were all sold individually - not in ABA sets. The sound system is in the B-unit, although both A and B have speakers, which gives a nice "stereo" sound . If you can't find a B-unit, you can always add Pheonix, Sierra or QSI sound system to the A-unit - probably considerably cheaper than buying a second-hand B-unit!
I found this on ebay and it appears that it was sold as an ABA 30 year ann. set in Baltimore & Ohio only. (LGB 70457). Sells for big bucks. So I think I will look for just a sound unit BUT if you live in Maryland, have an EX, and have the 70457 you might check the box because somebody's EX sold the A unit not knowing what its worth. Contact me because separating a man and his train just isnt right...
The B&O ABA came as a set. That is how I bought mine. Other LGB F7s did come separately. Several years ago Nicholas Smith was selling the see through F7 A and B units at a price that I couldn't pass up. They were sold separately. If he still has some you might be able to get one and paint it to B&O colors. The see through units, with all the flashing lights are a hit with the kids (of all ages) at our Christmas show in northern Virginia.
I moved the sound from a B unit to an A unit. Just happened to be a B&O where a person wanted to run an AA unit with LGB sound. Used the sound from a UP B unit.
I was able to move the special axle for the motor sound to the A unit and make the A unit feed the speaker in the optional second A unit.
