I have 1 pair of these from the AV123 auction that I am looking to sell, the others are for my own projects. Each board ran for 5-10 minutes while hooked up to components and performed wonderfully with zero cap/resistor/inductor issues or tonal changes/odditites. I can ship ups or usps flat rate and expect it to be $10-15 given their weight/size. I am at work currently but will post photos of them later this evening, and of course can take paypal. Thanks!
