A step up from the JD 502CRC and the JD 302CRC. The circuit has been redesigned and placed in an all aluminum chassis. Parts of the unit have been upgraded to include ESA clarity coupling caps, high speed diodes and naked Z resistors on the feedback loop which lowers the noise floor and enhances air and dimensionality. Flexibility is a bypass that allows the amp to be utilized as a power amp and the ability to switch between EL34 and 6550 vacuum tubes. You choose the tubes you want with your order Prices will differ between EL34's and 6550's.And for the best part, a clear, smooth sound with the air that vacuum tubes can deliver. Please note all Jolida sales are final sales with no returns.
Sales Policy : All sales are final no returns accepted.If any Jolida shipment is refused and or returned for any reason including a possible defect and no defect is found a 25% restocking fee will be imposed additionally customer will be responsible for all shipping charges to and from the shipping point.By placing an order you are accepting these terms. If Free shipping is offered it applies only to domestic U.S. locations.
