 I have got the CCS kit from Kevin over a year ago and never got the chance and mood to install it until now.

I install the CCS to replace the cathode resistor R6 (15K resistor) for long-tail differential pair for the driving tube.

The result has been very positive. As Kevin advised, the CCS forced equal current on both side of the tube and no need to have different anode resistor (22K and 24K) for the tube.

The music was fuller and sound more natural and musical. Highly recommend others to try out this enhancement.

Thanks to Kevin to provide such as simple but effective kit.

 Welcome to the club. Always pays to listen to what Kevin says.
