Black Ice Audio by Jolida - Fusion 3502S Vacuum Tube Integrated Amplifier

If you're unfamiliar with Black Ice Audio you may know the brand better under it's former name Jolida. This unit has been fully tested by one of our technicians and is fully functional. It is in like new condition and comes with the original box. It comes with Tung Sol 6550, Electro Harmonix 12AT7, and Tung Sol 12AX7 tubes. The original remote is also included.

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.
