Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

HK Ratings

The rating for "heater negative with respect to cathode" is a problem for the majority of possible subs in cathodyne service. With +400V B+, voltage on the cathode of the splitter will be around +100V DC in addition to 60V AC pk-pk signal. It's not clear to me yet whether I'll elevate the heaters in this driver. In any event, I don't see much reason at this point to look for a different tube type. I have a decent stock of 6C4, and this tube has proven it's capabilities in this service in many commercial amplifiers. I have bigger problems at hand right now, like aligning 3D dimensions in the various chassis pieces using 2D software. :)
