Even in today's modern in-the-box realm of recording, the Fender Princeton Reverb, especially the vintage ones still stand a solid ground in recording electric guitar!

We change out the electrolytic capacitors, and also end up replacing the octal tube sockets after an attempt at re-tensioning the pins in the original sockets. These were worn-out, unfortunately. 0:00 Introductie 0:21 Visual Inspection 2:35 Disassembly 7:01 A Service Plan 8:43 Happy Soldering Time! 15:42 Surgery Recap 16:08 Cleaning Pots & Tube-Sockets 22:02 Bringing it to life 26:45 Output Tube Bias 33:25 And more soldering! 34:19 DEMO We are lucky: This PT is a double-120v example and the JJ-5U4GB miraculously gives us the right voltage for a newly installed set of JJ-6v6 in the original non-adjustable fixed bias setup! Too high current draw could cause low plate voltages but it's good that's not the case. A GZ-34 takes it closer to the given value on the schematic anyway but the amp works great in this conservative setup. In this video I'll show you how to calculate the bias in these. The original Blue coupling capacitors also test fine and are not leaking (yet). While the amp might benefit in the future from a preventive replacement, it's nice that it's further fully original and working great. We do modify the tremolo as it is a very easy and reversible mod. The original value of 1M didn't quite cut it, even with the intensity on 10. This is a common mod. Gotta love these old Princetons, which aren't critically altered since the blackface era. When pushed a little and played with the right touch it can give you a wide range of great guitar tones with just your attitude and electronics on your guitar!
