Your the one who advised him without technical knowledge to throw a small fortune in Jupiter, Deulund or Mundorf capacitors into it, without even knowing the circuit parameters of this unit if they can work with it or not.
Please tell the owner and myself, exactly in what position in the circuit these Jupiter, Deulund or Mundorf caps should go and which caps they are to subsitute, and what value in uF and V they should be??
Cheers George
