[Hammarlund] Capacitor replacement

[Loren Burkett]

I think Chuck Ripple (sp) did not like clipping out the old caps.  I do like it as it does less damage and makes a cleaner job.  The anti fungus coating is a factor also.  The heat gun on the bathtub caps was a mess for me.  Even though it changed the look I removed them in my last one and added terminal strips.
