I know this thread is over a year old, but....I found it and it helped me tremendously!
My 2230 was sitting in the closet for over a year because of the same loud crackling described by the OP.
I replaced all of the xistors on the P400 filter board and it solved my problem too. I just had to say a huge thank you guys for giving me my beloved 2230 back!
