There is potential to replace the HV capacitor in the CLS IIz speakers. ![]() There is one Electrocube brand high voltage capacitor in the CLS IIz speakers -- in different units I've noticed there are either a set of 0.005µF capacitors in parallel (to equal 0.01µF) or a single 0.01µF unit. ![]()
side note:
The specs for the Electrocube capacitor: electrocube miniature HV capacitors, 520-series If you care to replace this capacitor, here is one option: Allied Electronics -- ASC 16kV 0.01µF $10.82 each. They also have 0.02µF units in stock for $12.93 each. Vendor datasheet - X675 series metallized polyester tape wrap and epoxy fill case Web searches for other HV capacitors show that there might be other brands with similar capacitance and voltage rating that may be suitable for substition. Note that placing multiple lower voltage value capacitors in series can increase the voltage rating of the string but good engineering practice would include equalizing resistors -- which may adversely affect the ESR rating of the string.

![]() Illinois Capacitor 103MWS103KT -- 0.01uF, 10kV This is stocked via several distributors. It is approximately the same size as the Electrocube unit that it is replacing in the CLS IIz.
Again note, there is no bleeder resistor on the 10kV circuit. I used
a 100x voltage probe to check voltage prior to start:
The black Solen capacitor is completely bypassed in the 'flat' setting or with the jumper installed and has no effect on audio. This page last modified Mon Aug 25 21:36:59 CDT 2014 by timc! |
