11ES4 replacement

[Paulok]

Hi,
Apologies for being a complete novice but I'm looking to replace a few 11ES4 diodes in an old organ amplifier board but cannot find them and don't really understand much about what I could replace them with. Is there an available equivalent I can use?
Many thanks
Paul

They look to be 600V 1A rectifiers, so 1N4007's should be fine. Lower voltage versions 'may' be OK, depending what they actually do - but personally I've always only stocked the higher voltage versions of rectifiers, as it replaces all the lower voltage ones as well.

Thank you
