Resistors


How often should these be replaced in Wilson Sophia 1s?  Purchased these in March ‘19 and did not inquire into whether they had ever been swapped out.  Is there a great benefit to this?

visually, you can see a transistor that has bone bad, you will know when you see one.

otherwise they last forever, most of mine from the 1960's are good, a handful replaced, cheap, easy solder job..

typical +/- 5% of their stated value in the old days, now +/- 2%,

can you hear the difference?

Thanks adg101 - didn't know Wilson used resistors for fuses. You are correct I haven't owned any. No one I know uses "fuses" in series with any of their drivers.

I think I responded similarly to another poster a while back and was told this is a recommended PM by wilson.

Good info on this thread - thanks.

I am also looking to replace the resistors in my Watt / Puppy 6's.  

Is there a trick to getting the access panel on the Watt (top speaker) removed? I got the six screws removed, but it seems like there is still something holding it on. Any ideas if there is glue or something still that needs to be removed?

Interesting you should bring that up Zerofox. I contacted Wilson about the resistor issue I started this thread on and received this response:

Truthfully, the most challenging aspect of the resistor change is removing the access door - after years of high tension from the screws, the gasket can get quite sticky and it can feel like it is glued in place. The key is to remove all of the screws and walk away for an hour while the gasket starts to breath and open up….some have had to use a bit of heat from a hair dryer and I usually have to insert two Allen wrench drivers to gently pry the plate off and then you can insert the tools just inside the screw hole opening and apply downward pressure.  The plate should pry free.
