LED A3 to Center Pin not lit

[Paul Birkeland]

You should be able to test the red diodes with your meter on the diode setting (With the amp off).  The meter should give a voltage reading with the probes one way and nothing with the probes the other way.  Let us know how they measure.

The diode shows voltage both ways!
.240 DC V negative probe to marked side of LED
.623 DC V positive probe to marked side of LED

It was my understanding electrons should only flow one direction through a diode. Is my problem as simple as a broken LED?

Although I rarely say this, I would recommend replacing them both.  If you have an adjustable soldering iron, turn it up all the way when you solder the new LEDs in.  If you don't have an adjustable iron, then get a 45+ watt handheld iron.  The LEDs are OK being exposed to the ultra high heat, provided it isn't applied for all that much time.  It's much worse to use low heat for a much longer period of time.

PB,

I was caught up with work and school but I finally installed the replacement LEDs. This solved the problem. The crack is humming. I installed the Speedball. Its working great!. I love this amp.

The crack is humming.

Hopefully figuratively!
