Had my Creek since 1984 - absolutely brilliant !! However, I think something has gone phut and blown my Mission 70S's.
When the speakers load after power up, they rustle badly and hiss like excessive static, then they don't play anything.
Just bought some new speakers (AE Evo1 Aegis) and have tried connecting them to the Creek, they rustle very slightly but hiss over the music. Need to fix this before driving them for real.
Any ideas would be much appreciated - the amp is too good to give up on.

It seems that you have a low Hz feedback loop between the speakers and the tonearm/stylus.
Usually it's only a visual effect and very little can be heard.
In the old times there was a "subsonic" filter in the phonostage part of the amps to cut this out.
You could try a different placement of the turntable as this phenomenon is induced by airborne vibrations and a different placement could ameliorate this interaction...
If it works on the other channel, then you have a faulty amp. If the sound is good on headphones then the left power amp has gone. If not then you have a left pre-amp problem.
If the speaker doesn't work at all on any channel, then either there's a bad connection inside the speaker or one or more of the internal speakers have blown.
If you were playing with the speaker out ----off sure the amp IC is blown or the related circute problem as occured
if you smell the shot circute ...tipically a silicon burn smell....then ...there is a problem in side....
remove the cover and physical check for the blown parts using a tourch if you fing any parts or the bord blackning.........
fault may be there\
some times with a small blown fuse replasement ...cure's it .........
It's the ribbon cable that is likely at fault. There are actually three computer type ribbon cables in the amp. I believe the cable that is responsible for the drop-out of a channel is the widest (longest) of the three, but you really need a tech to look at it and replace the cable. But please note that the new cable may also have defects in manufacture and that it may take some time to order a new cable from Creek. I had a tech solve the problem permanently by removing all three ribbon cables and then hard-wiring the connections together - that is to say, point-to-point wiring. My cost was about $250, but as you can imagine, there is extensive labor involved. Good luck!
Are you saying its taking a long time for the sound to come out of the speakers?? or that theres no sound at all?? If its taking a long time check the resistance of each speaker to see that a componet in the crossover or the speaker didnt short.If you take all the speakers and if theres supost to be a relay for protection and you hear it click then the amp is good or has an out put stage problem like bad poutput devices or blown driver transistors. Need alittle more info if you could Thanks.
