IBAM Preparation

First, I put together a modified schematic of the output circuit showing the necessary changes for the IBAM mod:

And then I built the actual IBAM board, then called it a night last night.

Tonight after work, I started preparatory work on the chassis to get things ready for the IBAM circuit.

Since I had to remove some resistors, I just went ahead and replaced all of the resistors in the area of the output tube sockets.

I will next install the new 10 ohm cathode resistors, then I will hook up the IBAM wires and we'll see what happens after that.
