   2013 is an unfortunate year number. Remember 1913? - a terrible lead up to WW1   
   and countless bloody deaths, so how much longer have we got until shit happens   
   again?    
      
   So, just like there's no stop in some elavators for Floor 13, methinks   
   positively about 2012A, after which we could move directly to 2014, although   
   it would then feel like a jolt. Even if you leave out an unlucky year, you   
   will still feel something went    
   missing.     
      
   Meanwhile, I bury the hatchet on New year's day, as I have to on Christmas day   
   when some merry discussions around a dinner table ensued.    
      
   But this NY day I do investigate the use of humble EL34 in SE pentode mode to   
   drive a complementary pair of source follower mosfets in class A (of course)   
   and then there is NFB using 100% of output signal to EL34 screen, to thus make   
   the EL34 operate    
   like a triode with gain about 9, but included in the triode strapping of the   
   EL34 pentode, I have the whole mosfet output stage, so both THD of EL34 in   
   pentode PLUS output mosfet stage is much reduced. So thus with ONE pentode,   
   and fitted with CCS using    
   2SK1924, I have reduced the THD and bettered the bandwidth and increased the   
   damping factor without using an OPT, and only using 3 devices in what has to   
   be a simple circuit.    
   Analysis is underway, a little slowed by this New Years's Day intake of a very   
   fine shiraz made well by my countrymen in Sth Aust.   
      
   I wish all those who dabble in tubes and various ways of coaxing them to give   
   us pleasure a very fine year.
