Help with BOSS-CE2/Corrral Chorus.... Part question

[fs2o]

Hey folks...

I'm new at building my own effects. I have little knowledge of electronics, but I've successfully completed a few easy projects...

My questions are rather simple though:

1 - What is the Rin (resistor I assume) on the Corrral Chorus layout? What value is it? It's on the lower left side of the collored layout: http://www.tonepad.com/getFile.asp?id=101

2 - What does the RD11EB didode do (can't find one anywhere)? What about the IC TL022 (also can't seem to find it)? Are these usually hard to find?

Thanks guys!!!

regards from Brazil
