I ordered the transistors directly from the manufacturer, when i build mine
in 81.  They had a $50 min. which was satisfied by my order.  
You might also be able to get them from Old Colony (associated with the mag.) 
One other thing you could try is to look up follow-on letters going well 
into the 80s.  I think he published an update on the amp and i think he 
mentioned something about output devices.
