[TowerTalk] Looking for UST Control Box

[Les Kalmus]

Thanks. I think those may have been used on older towers. I have them on 
my older UST HDX-589MDPL but a newer HDX-572MDPL has Allen Bradley 
802T-AP series J, switches marked type 4, 6P & 13. I bought one on ebay 
new for about half of UST's asking price. They sell in the range of $80 
and up which is why I was wondering how you got yours at that price.
