Rat Mods Thread

[soupbone]

I was looking at this rat mods thread; http://www.diystompboxes.com/smfforum/index.php?topic=91080.msg776103#msg776103  I have a chinese made rat 3a rev b(If you scroll down from the linked thread mine looks just the picture the 6th post down).I was going to try ryanuk's mods(a little further down on the same page),But i don't think the changed parts he did match up with my board.Anybody know what Ryan is changing them from?

The original part numbers are from analogguru's schematic: http://analogguru.an.ohost.de/193/schematics/Proco_TheRat-1986.gif

C1 – from 22n to 220n
C2 - from 1uf to 47uf
C8 – from 4.7uf to 10uf
C7 – from 30pf to 47pf
R10 – from 1.5k to 22k - 1.5k was for very early rats - most rats are 1.6k - Chinese rats could be something else as they apparently changed the filter - so your C9 may be different as well (not 0.0033uf) - all this change does is turn up the filter (the min and max settings are higher)
C11 – from 1uf to 10uf - this is the original rat to rat2 change - yours might already be 10uf
