Anyone with Manley Chinook use a custom Power Cord?

Thanks!  Yes, that is likely what I would do.  But, I'm wondering if it's worth the expense and effort?  Would it make any difference on a phono pre?

Thanks, @johnss !  What do you mean "grunge"?  I've read that those aren't in the signal path, so I'm curious how they impact the SQ.  I agree it's easy, and less expensive than a new PC.

 @johnss  I think you mean the duals. Those suckers are $80 each?!  So that’s almost $200 after tax and shipping.  Is the difference that great?  

For that much I could buy a set of NOS tubes, and they are in the signal path, so can have a huge impact. 

The stock opamps are about 30 cents. So maybe something that costs around $10 to $15 would be a nice improvement without going overboard. What do you think?

@slaw I agree that I don’t want to do any soldering or anything that would void warranty. I can see how they could help, but I like warranty! At the same time, I’m not convinced by a $150 fuse. It could work, but hard for me to conceive. I’d try it for $30 but not $150.

@mattmiller 👍 yep. I ordered a signal cable digital PC. Should be here in a few days.

@johnss this sounds interesting.  And, I think it’s more likely to make a difference using the MC setting, as I am. Since it drives the higher gain input, I can see your point and understand why it could help. I think I will try that next. Did you get the dual or single op amps?

If you are reading this in the future, this is an interesting read about op amps. I’m not expressing an opinion, only sharing what I found.

I bought a new new set of tubes to roll, and the signal cable power cable. After I get those going I will report back... and I’ll decide about the op amps. 

@lewm I hear you and completely agree!  I'm not sure about the output cap, but I'm not likely to mod something like that, which may end up voiding my warranty.  Anything I do has to be able to go back to factory without being permanent.

By the way, @lewm the power cord I bought was $69, so not super expensive.  We'll see if it helps in any way...
