K250-4 amp rebuild parts
http://www.vintagekustom.com/FUDforum/index.phpindex.php?t=rview&goto=27629&th=4767#msg_27629
I'm trying to source ALL the devices for a complete
pre-amp/amp rebuild for my K250-4 monster
I've replaced the two 'big can' electrolytics'
and I'm starting in on the two pre-amps
The first obscure part is one 14pin DIP dual op-amp
XR4739/nte725 uA739
The amp DOES work but it's noisey
and the high end distorts when I
play my Wurlitzer Electric Piano thru it
