General purpose op-amp - try a TL071

Could someone confirm that?

Sorry, the description was GP Opamp - its actually a switching op-amp which is why I edited my post.
Supliers are available but they seem to be a bit limited availability ...

A quick google showed they are a proprietary chip for Marshall, and have to be ordered through KorgUSA. The NJM2120 appears to be a replacement - datasheet here . They look the same to me ...
