4 Ways to safely direct couple in tube amplifiers

In this 29-minute video, I'll go through 4 circuits of which 3 feature safe direct coupling between amplifier stages and 1, the Loftin White, which can be made reasonably safe as well. With safe I mean that failure or unplugging of the driving tube has minimal or no effect on the longevity of the output/driven tube. With 'reasonably safe' I mean the tube will remain within the rated dissipation limit of the tube. The 4 circuits discussed: 0:00 Introduction 2:23 Directly coupled Cathode Follower 8:08 DRD / Monkey Circuit 13:13 Loftin-White 20:56 Dynamically Coupled / a Safe Loftin White
