I'm Jim and I am the proud owner of a ST-70 of unknown origins.
Picked it up from a pawn shop for $200. Plugged it in and it plays.
I think the sound can be improved, so I have been doing a lot of reading.
I'm looking at the pc3 board and i see someone has done a few mods.
The .1 have gone to .2ufs and the .05 have got to .1 uf. I think that is all ok.
However the 82pf have gone!
Is anyone familiar with the mod. Just go with it or do some more work here?
Here is a pic.
