Accessory Voltage Controller

I have received a number of suggestions as to how to fine tune accessory voltages on the electrical forum.  Thanks to all. Will advise which methods I use.  My current quandry is determining what use I can make of an Accessory voltage controller I bought

probable ten years ago and never used.  I downloaded the owners manual from Lionel and have read it several times.  I have found a number of questionable statements and important omissions in the manual as to how to install and operate this controller.  I have e-mailed my questions to Lionel with no response to this point.  No one on the electrical forum has mentioned any experience with this device. Am I the only sucker who ever paid over $100 for this paperweight?  IF THERE IS ANYONE WHO SUBSCRIBES TO THIS FORUM WHO KNOWS HOW THIS THING WORKS, PLEASE CONTACT ME.  Obviously this unit never gained much popularity since I have never seen one referenced in any post, and it seems to be the only TMCC accessory device which has not been the subject of a Utube video in Lionel's series.  It was shown in an overview of TMCC control devices, but is the only device which was never made the subject of a video.   Please help if you can.

Never did think this product was worth the money because of the obvious limitation. It only provides a single accessory voltage.


I use one of the older K-Line Accessory Transformers which can provide multiple voltages from from 5-18 volts at 120 Watts. Got it for $70 and it is well worth it. Justrains had them a few years ago for $50 but sold out quickly.


You might just do a search on E-Bay for one of these and forget the AVC or just use it to provide a single voltage for lighting.

The AVC lets you program multiple voltages, but only one at a time, since it has a single output.  I agree that I could never see the utility.  You can pick up the little 30-40 watt transformers for $5 many times, a bank of those would make more sense and you'd have multiple voltages continuously available.   The old Lionel transformers like the type V or Z that have four variable outputs also work well.

I have all the boxes but the AVC, because like John said, it has a single output for voltage control, and there are better ways to power multiple accessories.

IMO; Just buy a old train transformer. You can get them from $5 for real old to $40 for fairly new.  Don
