19AQ5 (19AQ5) 

Hello, I would like to update the 19AQ5 to include additional Similar Tubes which aren't back-linked. The page for 6AQ5 lists several variants (5, 9, 12AQ5) in addition to the 19AQ5 but these are not reflected on the page. Thank you.

Heater variants 

Dear Joseph,

the  6AQ5 is correctly linked to its several heater variants, considered as derivatives of the same prototype. Of course, even the heater variants are linked back to their forerunner and this can be useful to consult the many data sheets and curves available for the prototype. A cross-link among all the heater variants is of limited usefulness, since different heater variants are not interchangeable.

If you want know how many heater variants were built for the 6AQ5, simply launch a search for tubes 'Containing' the characters 'AQ5'.

Regards, Emilio
