Fusion 3502 S with 6550 Vacuum Tubes
Combining a JD 302CRC and a JD 502CRC has resulted in the Fusion 3502 S. With a flick of a switch, you can set your amplifier up to operate 6550, KT 88, KT 120, KT 150 or EL34 Vacuum Tubes. The circuit has been redesigned and placed the same venerable steel chassis. Parts of the unit have been upgraded to include ESA clarity coupling caps, high speed diodes and DC voltage to the preamplifier tubes which lowers the noise floor and enhances clarity, air and dimensionality. Flexibility is not only the Vacuum Tubes, the Fusion 3502 has a bypass that allows the amp to be utilized as a power amp. You choose the tubes you want with your order. And for the best part, a clear, smooth sound with the 3 dimensional air that vacuum tubes can deliver.
