Building an amp

19 - Modification

Mods

After reading multiple topics on the Weber Forum, I've decided too do some modifications:

• 1 - Isolate the inputs.
  See page 30 Grounding Scheme.
• 2 - Bias resistors and measuring points.
• 3 - 1K5 grid resistors with more power.

Narrow Fit

The holes for the bias measuring points.

Thank You Nico!

Resistors

Resistors etc. connected:

1K5 grid resistors (green).

1 Ohm bias resistors.

Inputs

Isolated the inputs, because of my grounding scheme, see page 30 and the next documents:
