Jolida Fusion 3502 S  or Fusion 3502S

Combining the JD 502CRC and the JD 302CRC. With EL34 tubes it looks just like the JD302CRC and with 6550 tubes like the JD502CRC. This amp can handle  tubes, 6550 tubes, KT120 and KT150 tubes. Jolida sells the amp with either the EL34 tubes, or 6550 tubes. You can buy the amp without power 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 Jolida Fusion 3502S 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. The Fusion 3502S amplifier has MSRP $1799 with 6550 tubes($1695). MSRP $1675 with EL34 tubes- our price now is $1595. This amp also comes as 3502P – power amp. The Fusion amps all have the level 1 upgrade components- ESA clarity caps, Hexfred diodes, and Vishay resistors. The Fusion amps sound very clear, natural, and smooth. Very nice sounding.
