Looking for Power Supply for TUNZE 6101. Part # is 6101.240 willing to pay for shipping

Looking for a power supply for Tunze 6101. Model: 9935 order no. 6101.240 please pm me if you have one to spare. Thanks.

I have a Tunze 9935 power supply that runs a 6101 pump. It is now not working. I have two so I did the whole swap process and still no go. It is about one and half months out of warranty, so I decided to open it to see if it had a blown fuse. The fuse was fine. Anyway, can anyone tell me how to...
