i like that idea NZ8N.

is this something that you just came up with or something you've been using for a while?


CB590,


the reason L13 doesn't have a slug in it is because it's just a coil to keep RF off of the DC voltage supply to the collector of the driver.  a slug would do nothing for it.


my guess is that small cap is C45, which would be somewhere around 33pF.
