I am having trouble getting some help with something from your website on modifying the President Washington uPD858. One of the modifications says to pull the AM regulator and toss it and replace it with a beefier transistor. However, you give the part# 2SC1419 but do not say what TR it is on the circuit board. I can't find the 2SC1419 in my radio.
Please see if you can help.
