RE: what CCS for a 6sn7 driver tube

Posted by JKT on January 10, 2017 at 11:47:06:
If you are using an Aluminum chassis and the dissipation is under a Watt you could purchase the attachable CCS kit and use the chassis for a heat sink. For performance considerations I would recommend the cascode version. You will want to allow ~30V headroom for the CCS plus the anticipated P-P signal voltage swing on the output of the 6SN7. So make sure your B+ supply is sufficient to allow for that.
