Klark Teknik D780 reverb - Popping sounds

It is making random clicking and popping sounds.

I recapped PSU and elcaps by the IP OP section.  In the IP/OP section I swapped opamps with OPA-275 but I can't recall the original ones so I plopped 5532s in there.  And the 5532s made no diference.



PS -I thought it was my boards or speakers and I finally found the culprit -excuse the chaging subject heading

we had an HR-24 at work. It died in less then 2 years but in all fairness was left on 24/7. Gave an error one day which the mackie website said was a general error then on reboot drifted gently to that harddisk recorder heaven in the sky.

I canĀ“t help you but I had similar problems with my 780 but they disappeared after recapping.

Output converter is common on these... so is the input converter.

I have a KT DN780 here that also needs a converter... they're rare and expensive!

Thanks for the info.  Could someone do me a huge favor and tell me the opamps on the IP/OP PCB there are 2 on mine and I swapped them.  IIRC they were 5532s.

I recapped the PSU already.  Damn I bought this less than a year ago on ebay.
