Default Re: Amplifier problem (record player)

Hello everyone,

I have touched the control grid only to obtain a fairly weak hum even at full volume, but not measured the cathode voltage, and it does have an electrolytic cap 47uf 40V. The strange thing is though, before I replaced the stylus it did play very loud so I am not sure as to what has happened.

But if it is the cartridge as Edward suggests then it will have to sit on the shelf until something comes along.

Best wishes

Ken
