x250 vs. x250.5:

mosfet vs . tl431 bias gene
4 vs. 5 outputs per quadrant
probably different UGS generation


for 350 - I'm somewhat unsure - there is old variant - mosfet non UGS FE , 6 pcs outs per quadrant , then possibly variant with UGS (mosfet bias gene , dunno for number of outputs)
350.5 - UGS , mosfet bias gene , 6 outputs per quadrant

so , Pa is your man for definitive answers
 
Simply ask Papa what are the possible improvements for your amp. He will advise you in deceptively simple language and you will know exactly what you can hope to achieve. He is a master of language...nothing is hidden or unclear. How he achieves that completeness of transmitting his message with such clarity and low word count is an exceptionally well honed skill.;)

Just interested in fixing up the front end, if I decide to proceed with this idea.
