President Ronald Mic Socket Fault

Post by Phuture »

Hi,

Working on my President Ronald and inexplicably while trying to do a SSB linearity check and adjustment the axial high frequency inductor got fried and is now open circuit. :shock: :oops: Would anyone know what the value of L501 is on the small mic socket PCB?

Here's the schematic I'm using:

Thanks

Hello

L501 LDD205 replacement by VK200 or similar

Hi Claude,

Thanks very much for your reply - very useful.

Are the number of turns in your photo attachment the actual number required? It appears the VK200 comes in four different values so I'm not sure which one would be suitable.:

I also found a T1 thread in which BigPimp quotes someone saying they believe L501 is a 5.6uH inductor:

Thanks!

Okay, thanks, Claude. There are so many different schematics that it's difficult to know which one to follow. Thanks anyway.
