The 6T5 and 6E5 only need ~ -8 volts to close, while your set is supposed to provide ~ -22 volts for a 6T5.  That means you're pretty far off.  I'd try the alignment while monitoring pin 3 like Terry suggested previously. 

If you get the voltage back to where it should be the 6E5 might even be too sensitive on stronger stations, but let's see what an alignment does.
