1964 Princeton Tube Replacement 

Informative and interesting. Nathan does a great job of explaining without talking down to the audience. More vids like this! ❤️🎸

I went through the process you describe in this video on my 79 princeton reverb . The tubes are new JJ's. Using the calculations provided I came up with the following numbers. Tube 1- 148,2 ohms-5,99 voltage drop-.040 plate current -398 plate voltage-15.92 watts plate dissipation. Tube 2 -151.1 ohms-5.99 voltage drop-.039 plate current-398 plate voltage-15.52 watts plate dissipation. Do I need to be concerned about this? If so what do i do to bring the amp into specs?

Thank you very much. Excellent video, I appreciate people that are willing to share their knowledge with others! I think it could be very helpful if you posted a video showing us how to use Ohm's law and how to use the formula that relates power, current and voltage to calculate all the values.

Love shit like this. Electronics and listen

Good simple vid! Thanx!

The non-reverb Princeton is supposed to be clean. Nothing wrong with this amp.

shame to put JJs in such a wonderful amp, it deserves better

It runs push pull output that causes. Less distortion. If you want more distortion use a single ended output.
