FAQ 219-2002-en

I have a line amplifier ref 5060: what can I do to disable the VHF amplification?

Respuesta: 

You have to carry out two quite simple modifications inside the amplifier:

  1. Remove the 470 PF capacitor (No.1 in the picture)
  2. Solder it in parallel with an 8P2 capacitor (No. 2 in the picture)

In the picture below you can find these capacitors on the PCB.

By removing the first capacitor, the VHF path is interrupted.
The parallel of both capacitors minimises the influence of this stage in the output.

Another alternative is to just remove the 470 PF capacitor and solder a conventional 47 NF capacitor in parallel with the 8P2 capacitor.
