something I could apply myself?   I am going to be doing the bass-fix and it

I think it is  C1767 on page 4:

Thanks, that looks reasonable.  Before I can try it I need to get some 
parts to build a capacitance meter so I can find some appropriate caps 
in my junk bin.

hi ben,

sounds like a very interesting and useful project for an old freerunner board. 
Do you have a blog set up to follow your steps/success? that would be great.

best regards and happy new year you and this extremely innovative community!

robin
