Grado Headphone Amplifier

Is anyone familiar with this headphone amplifier?

As I get ready for some overseas business travel, I have been dusting off some of my portable and travel gear, and I was disappointed to discover that my headphone amp has dropped one channel.

The RCA jack in the back appears to be loose - as it twists around and around - perhaps the sign of a broken connection. But I cant figure out how to open this thing, and I am wondering if it is worth the trouble to send back to Grado for repair?

Does anyone know how this might compare to other headphone amps? Or if I send it in, if they might be able to perform some updates? (I have had this one for many years, but have used it very rarely.)

Thanks for any thoughts - would use this with an iPod, and/or a laptop, with Sennheiser PXC 450 noise reduction headphones on airplanes.

I had the same issue with my ra-1 with a loose rca connection (still worked) Grado repaired free of charge.

Mention if they will add some glue to the existing connection to prevent it from happening again.

I do think it is a great amp and I get very good results with my Ultrasone 2500.
