Re: Most Minimal Superhet
Hello.
The ECH81 is reckoned to be the best FC that was made. On a conversation a couple of nights ago I was told that some of the octal based and equivalent valves don't make the best Anode Bend Detectors, allegedly the EF80 & EF91 work very well indeed. As far as I have been told an Anode Bend Detector has a zero point that needs to be above before any audio is produced, it is its downfall. With a BFO it works well as the carrier from the BFO lifts the detector above the zero point, it works well on my mate's home made set.
