Fry Pro II
« on: 1 Feb 2007, 09:34 pm »
I just ran out of chassis part for the original FRYKLEANER PRO machine.  So I decided to take the opportunity to upgrade the concept a little bit and make it even better.  Ok, this new version does require more work on your part, but is a heavier and more robust unit.  It is also more amenable to customization.  Add whatever connectors you want.  There is available space across the top.



The instructions are contained in this new article:

Jim,

Great! A chassis to look forward to as an upgrade in the future.

After reading your article/instructions on the Fry Pro II, it seems like I have been breaking my cables in with 'current mode.' What are the advantages of 'voltage mode' and do you recommend 48 hours in voltage mode and 24 hours in current mode for all cables? Any recommendations for other components like phonostages, line amplifiers and main amplifiers? Especially with regards to break in time? I guess this really depends on what capacitors are in each of these components since they can take the longest to break in.

What do you do for breaking in DACs? Use a recording of the FryPro waveform on repeat (either computer USB or regular red book transport)?

Anand.


Thanks,
Anand.

Actually, the original FRYPRO was wired differently.  It was a hybrid that did both voltage and current modes at the same time.  I had thought it was an improvement over the original FRYKLEANER.

But now I am thinking it may not be as complete.  So I am reverting back to doing both modes separately.  I haven't proved it, but suspect it might be a little better.  More hassle for customer, though!

What I have discovered is that current mode is the secret sauce.  That's what makes this machine work so well.  It was all an accident on my part.  Anyway, I changed the wiring so that current is driven on all conductors and shields for maximal benefit.  Or so the theory has it.  Voltage mode is still a good idea. 

The numbers are empirical, based on feedback from customers.  Two days current mode was the sweet spot.  Add another day or two voltage mode and the cable has radically improved.

Oddly, I think these take less time.  24 hours is often dramatic enough.  But that's not the opinion of everyone.  Some manufacturers (especially caps) say it takes 200 hours or even longer for them to settle in.  The good news is that I really don't think it is possible to over-cook an amplifier or cable.

Exactly.  I supply such a CD with the FRYBABY.   Download the file below and burn your own.
