Fixed

Got the SVT 4 fixed.
1 hour to take it apart.
1 hour to resolder the main board.(found a couple of really bad solder joints)
1 hour to put it back together.
1 hour to final test & do paper work.
Nice amp!
Why do people think this stuff is easy?

Yea. Everybody thinks the other guy's job is easy.
"All ya got to do is .... What's so hard about that."
"You charged me how much to solder two joints?"
Etc. etc. etc.

Glad you got the SVT fixed.

Regards,
Tom
