Re: copper cap rectifier

The prices of European manufactured NOS 5AR4s are upwards of $85 a tube and rising constantly. If it fits mechanically, the Mullard made GZ33 is an excellent substitute at about $40. NOS Matsushita (Japan) manufactured 5AR4s are another "affordable" choice. Matsushita bought their tooling from Mullard and copied Mullard's design.
