no, I just thought it wierd that you asked for places to rack your pre's and then answered you own question. anyway, it's a fact that caps lose their capacitence over time, doenst matter if they were over specd or not..it also depends on what pre's you have to. If they are tube pres then the caps will wear out more quickly due to heat of the tubes, but they all wear out over time. David does nice work, but I'm not sure about his 'transformer' comment... before you send your pre's to him though, ask him what kind of trasnformer he'll b using for the DI section. Ask him if he'll check over the pre and make sure it's working properly. Do you need a power supply for your pre's? Just curious, which ones did you get? (you too shilat)
