DIY Hoffman kit squeals (Help!)

TonyDIY Hoffman kit squeals (Help!)
I installed the Hoffman plexi kit into my Bassman head and when the feedback wire is hooked up, the amp squeals like hell. Any ideas???????? I'm using the stock output transformer. The wire is hooked up to the + output.  
 
Also wired up the extra gain stage and can't get the 1st volume up past 1 without squeals. Doesn't matter what position volume 2 is in.  
Any help is appreciated.
