E7 PRR

I recently bought the E7 N scale from Precision Craft in the PRR scheme and was really impressed with the sound and pulling power of the A unit in perticular.

But unfortunatly I encountered a problem with my sound equipped loco.I e-mailed the gyus at PCM and they responded in a flash.Long story short I had to send the loco back to PCM for repairs.( great service gyus thank you)

Now I was wondering if any one else picked up problems with the E7 loco’s and what is the general feeling and views on the E7 PCM
