[Amps] SB-220/221

[Dino Darling]

I spent 2 days going through the archives here and learned ALOT about the SB-220/221.  Thank you to all the contributors over the years!  The information was invaluable!

I picked up a CHERRY SB-221 from the original builder.  It even has the original 3-500s which appear to be in good shape.  I have not brought it on line yet as I want to check it out first.  Its been in storage for a long time.

I'd also like to convert it to a SB-220 and understand I need some parts.  Does anyone have any spare parts around or can make suggestions to make the conversion?  I know I can order the two waffers from Harbach (he will take new orders on Feb 1).  What about the tuned inputs.  As I understand it, this is what I need...

Any help and/or direction would be appreciated!
