  1. Hi Geir,

    I just found your crowbar circuit here. I would very much like to know – if that is ok for you – how you calculated the required thyristor ratings and how much filter-C your crowbar supports. Would you be able to share a higher resolution photo of the circuit.

  2. Dear Frank,

    I was looking for a very similar circuit for use in my HF 4cx1500B amp. Would it be possible for you to share the PCB artwork and schematics so that I can duplicate the same, along with your tips.
