VIC Choke coil resistance with frequency
« on: December 13, 2011, 00:30:22 am »
Has anyone taken a good look at the choke coil readings in the spreadsheet that came with the pictures I sold?
I'm talking about the resistance readings taken at different test frequencies.
If you look at the loose coil readings,you'll see that the readings taken with a Fluke,measured @76 ohms.
Then look at the test readings taken at 10khz. You now see 1200k ohms.

That just goes to show how much resistance there is on the coils when resonance frequencies increase.So now we can see that at resonance @ 10khz,you have alot of resistance,which then leads to amp restriction.

Thought I would point this out.
