I have finally completed the crossover boards that were designed and produced by Tony (Gimpod). I must say, that as Jesse said, they are so easy a monkey can do it. It really is very easy (assuming you can solder well). At Tony's website: http://www.gimpod.com/partsp31tl.html it shows you where to place each component and the proper value of each component. You cannot go wrong. Tony has done all of the value work and placement for you. It makes this modificationreally simple thanks to the hard work of Tony.
I have included some pictures of the modification as well as a comparison of the two boards; A before and after comparison. The components fit much better on Tony's (as you can see). I would also again like to again apologize for the amount of time it took me to complete these boards. Tony has been very gracious and patient with me though. Thank you very much Tony for that and for these great corsoover boards for SDA series. If you own some compatible SDAs, get these boards!! You will not be disappointed.
