I'm new to this forum but have been able to find much helpful info here...thanks.
My tub just quit and I need a new control pack, can you help recommend an replacement pack?
Here is the info on the current pack:

Brett Aqualine
CM-104
cat#28-Z454NVX-gpm
120/240 volts
16/40 amps
60 htz
1 phase
250 series

I've been looking around online and ebay for replacement's but really blindly.

Thanks in advance

The 104 series is a rahter simplistic form of spa control, and if you are confident, you could probably repair your old unit at a much reduced cost. Just have to determine what it was that went bad.
