See a few on ebay.
I’ve had one for 10 years but only on a 12 foot test track. Once, as a test, it ran 12 engines varying from Athearns to P2K without a problem. The sound is not comparible to what’s now available. It has two settings, mode 1 for G scale, mode 2 for HO and N.
It seems to have a lot of power but I am unable to understand the power rating thats printed on the back.
It’s heavy so check the shipping costs.
