Yes crossovers have been rebuilt.
Also bypassing the attenuators and fuses helps free up the sound.Fixed value resistors have replaced the attenuators.
The woofers have had both surrounds and spiders replaced.New midranges from the last production run too.
Also the fibreglass damping can pack down so all this has been replaced too.
A lot of work and expense but the result is something pretty special.
Agreed not all tube amps will drive them.The Almarro318b has big SS type bass control.Also the humble but excellent Ming Da EL 34A/B drives them very well.
