Hey Elliot,

Is this an electrostatic, or a planar magnetic?

Thanks,

Chris

The Quads are Electrostatic.
My maggy's llla's are planers are sitting in the background
The Quads Stators are charged at 3 to 5k vdc depending who you are reading.
Any way I will be replacing the Diode board in the power supply, the caps in the xover.
Removing the dust covers, felt batting and eventually building a stiffer hardwood frame.
I like the look of the metal grills but these are banged up some and will been some TLC to get presentable
