As long as you also remember your 'other' friend, the RCA Tube Manual..!!
Most tube substitution handbooks are about as reliable as Drake's 'Voltage and
Resistance' tables! :-)
Two common pitfalls are different filament currents (bad for series strings) and interelement
capacitances. Of course using them at 20 - 30 MHz further confuses things, as in sweep tube finals,
look at all the 6JB6 variants that do not work well at 30 Mhz..

I myself had wondered whether a 6AU6 would function as a replacement in a pinch. Disappointed
because I just bought a "NOS" 6HS6 (!?) for 15 USD, and could have bought a 6AH6 for less than 3USD.
