Since my TAS unit gave up and crashed on me, I have planned on putting an ERR system in to replace it. I have installed several ERR system and they all seem to work well with the supplied speaker. Now that 3rd Rail seems to have changed some I will go to my spares first. I think with the electronics in the lead unit I am going to use the tether system for the speaker. I have used it already for the light in the non powered unit to make it directional.
Currently I have reworked the AA units by painting the trucks silver, and adding dull coat and satin coat paint to the cowling. I am now waiting for lights to come from Evans designs. I think the unit looks great and hopefully will sound great with the PA sounds from the ERR units.
