Repair shops for TMCC Powermaster and Base?

I know that Dale Manquen used to repair these.  Here's the TrainFacts Home Page, he talks about these repairs there.

From the home page:

Introducing a new service – Component-level repair of TMCC Controllers

 

If any of your customer’s TMCC controllers fail, now you can offer your customer a solution! Lionel won’t fix or exchange out-of-warranty devices, and you certainly don’t want to troubleshoot down to the component level. Now you can recommend that your customer contact MANCO for repairs.

Dale is the man.
