Its all about the Music
It can be an original doorstop, or a working unit with a lot of modern transistors and caps. The market has determined that WORKING is the breadwinner.
For current source stuff, find the sx-1980 threads by anderslober in the pioneer audio forum, it has GOOD, annotated pictures of what's removed and what's added.You're in some of the threads too, so you should remember a bit.
Ah yes I do remember that thread, I think a stumbled across it before, I figure I need to do it as one of the 2SK34's has been ejected before I got to it....I read EW's thread from 2007 in DIY Audio as he developed it. Great reading!!
This is good, a plan is formulating, this is one SX1980 that will not end up a door stop or boat mooring...
