[sdiy] source of 4560 or tl072 in sil package in uk in small quantities

[Peter Blackett]

Dear list,
I need to get hold of a small quantity 5 ( or 10 ) of the 4560 op amp in 
a sil package or something similar ( tl072 ? )
I used I think a njm2114 as a replacement a couple of years ago, but it 
doesn't seem to be supplied now by Farnell or RS components.
just wondered if anyone knew of a source of these sil pacaked op amps.
in case you are wondering what these are for, I'm repairing a skytec tec 
250 audio mixer.
regards Peter
