I bought a used tube power supply from TMR that was designed and made by a small manufacturer , The Music Room's packaging was far superior to the original manufacturers packaging. They had used a foam machine to encapsulate the entire product before putting it in the box. I've owned this power supply for 5 years with zero problems.
Policy changes at The Music Room TMR Audio
TMR has made a few changes to their policies which may interest folks.
Warranties for used gear is now 90 rather than 45 days.
Trial period is now 30 rather than 14 days.
There is now a restocking fee of 5%. Their rationale for this makes sense and seems reasonable. It would be nice if there could be exceptions to the restocking fee, such as cables and other products which don't need extensive checking for quality control. One result of this policy is that there is some more costly gear I would have tried but now am reluctant. I suppose that’s just a personal admission.
