Hi All,
         Our proel monitor keeps blowing all 4 internal fuses  The fuses are 4a on the high side and 2.5 on the low side. Can,t see anything burnt,so just wondered if anyone has any ideas. Michael.

Hi Folks, Can anyone tell me what Ic is in the input stage. Is it an LM 741. There does not seem to be a schematic available for these amps. I have hum from the amp output but nothing from the input. Seems to point the the opamp.Thanks.

I have a Lab series L5 amp and would like to recap it. Anyone know where i can get the caps from,as no one in the uk seems to stock them. The two large 75v 3000mf are the ones i am haveing difficulty getting.
