Follow-up post. Depending on how the socket is wired you could probably temporarily substitute a 6SJ7 instead of crafting a 6AU6 adapter. The 6SH7 uses both pins 3 & 6 for the cathode with the supressor grid internally connected to the cathode. The 6SJ7 uses pin 6 for the cathode and pin 3 for the supressor grid - not internally connected to the cathode. So, you'd need to jumber pins 6 and 3 to try the 6SJ7.  
 
The 6SJ7 characteristics are somewhat different but close enough to determine where the hum problem source is.
