If you remove it, does the current draw drop to nothing?

What's the B-E voltage without the transistor in the board?

With the 6488 removed the amp draw drops to 0.

The B-E DC voltage without the transistor in the board is +0.780v.

Something is driving it. It could be leaked electrolyte, a solder bridge, a defective component...

There was electrolyte on the board. A through cleaning got rid of it.

Does this amp need to be locked in the heatsink to power it up?

The heatsink doesn't do anything but dissipate heat in this amp.
