In Reply to: Those HY40's are rarer than Hens Teeth...... posted by drummerwill on January 19, 2017 at 21:12:53:
I suppose it pays to collect such stuff as it becomes available...and the only reason I'd worry about the 'power tube' flavor is in its cathode heating requirement. That it will tolerate HV, and substantial plate dissipation is of little consequence. Besides, it is only about 30% bigger than the 20B which was put up as a potential signal tube solution.
Along with the HY40, there is its bigger, higher gm cousin the HY51A and HY51B which are also not easy to find...:)
cheers,
Douglas
