@Norton posted:ZWC should come with 180 bricks which can be used for power by themselves. The part that looks like a ZW allows you to vary the voltage but many have proven to be problematic over the years. Before spending money make sure everything works. Personably I wouldn’t spend more than what the bricks can be had for.

Good advice. There was a breakable plastic control inside too, now I remember.
I think I would buy the new ZWL if my C broke. Or maybe just use the bricks with those TPC400s.
