Converting the Fender Princeton to Adjustable Grid Bias

>> YOUR LINK HERE: ___ http://youtube.com/watch?v=DirM9fuUhJo

This video demonstrates how to convert Fender Princeton and Princeton Reverb amps to an adjustable grid-bias circuit very similar to that in the Deluxe Reverb. The original fixed-bias circuit is thoroughly explained, detailed circuit drawings of the conversion are presented, the conversion is performed on a 1966 Blackface PR, and its 6V6 output tubes are biased using the new adjustable circuit, with a sound check to demonstrate no ill effects to the tremolo. To top it all off, Rusty (even more energetic than usual) makes a couple of appearances. • If you enjoy videos featuring classic vintage amplifiers, home-built electronic marvels, and clearly-explained technical presentations, then please subscribe to my channel.

It is based on information obtained from technical sites on the Internet, including EL34 World. I am only attempting to present this concept (in an easily understood fashion) to You Tube viewers.
