I have four Cree rectifiers rated at 600 volts and 7 amps each that makes a 14 amp bridge rectifier. Includes 1/2 height heat sinks. This will support a 120 watt per channel SS amp. Or use on your tube amp- no heat sink required. The Cree make no noise unlike standard rectifiers and perform as well as the best tube rectifier such as Mullard GZ34 on tube amps. $25 shipped to USA lower 48.
