The meshplate tubes are not built to WeCo spec, their maximum plate voltage being below the standard WeCo spec max of 450 volts. A few amps, like the VAC Renaissance amps that feature a Class A circuit and constant high plate voltages (430 volts), cannot use the meshplates.
The claim to fame of the meshplates is delicacy, transparency and finesse, but they have to be used in the right amp.
