I will throw out my experience with Modwright just as are reference point. I bought a used and quite old Modwright Pre-amp that had some issues with grounding. It was years out of warranty but Modwright not only repaired it but they paid for the shipping round trip twice (yes it took them two tries but in the end it worked out, and yes I was frustrated to be without a Pre for that long also). If you value honest service, integrity, and support of quality American products then you can't lose with Modwright. Just my $.02.
