Would adding an exterenal 47K load through the phono bring it on?

Posted by 3+4=5 on September 25, 2017 at 22:27:57:
The scenario you present is expensive.
Perhaps more than the op paid for the whole unit?

Would one way to IMO test your theory be to add a pair of 47K resistors. (or 49K? 50K added to the cartridge on the phono input, with the switch set to the 100 ohm setting.
SO running the op cartridge with an added 47K through the 100 ohm level of the switch.
Would this be enough to cause the same problem to show itself?

I am all about being cheap.
IMO if the op can use the preamp at 100ohms instead of spending as much or more than he paid.. I certainly would just use it at 100 ohms! The cost to fix it would be at least $700 to send it in.. plus shipping...
I have to assume he bought it used..And the final cost could be much more than that.

(I paid $600 for a SP-10. $1,500 for an Sp-15
The boxes alone would be at least $100 to replace. (ARC never sends stuff back unless it is in the original type boxes. So no original boxes when one sends the items in (two chassis set for SP-10 Sp-11 Sp-15, 40th anniversary), the extra cost is passed on for new boxes. At least $100 like I wrote.

I know Charles Hanson is a smart guy.. I just am hoping he is wrong!

I would still try cleaning the switch..
And if that fails, and the 47ohm added to the 100 ohm fails.. I would just live with the 100 ohm.. unless the op is rich enough to pay the $700 to $1200 a ARC repair would cost?
