Many of us start with a White Oak Audio Capacitor Kit to make the amplifier stable and reliable because the original Main Power Supply Capacitors are beyond their life expectancy, and the Rev G1 Dual Mono Control Board Kit. You can assemble the Control Board yourself (it comes with instructions and a Bill of Materials (BOM) that makes assembly a bit easier. That is what I call Stage 1 and it makes a huge improvement in the distortion, noise, and stereo separation in the amplifier.
Stage 2 is the jump to a "Full WOPL". Everything above and a new Bridge Rectifier, a White Oak Audio Backplane Kit, and new Output Transistors to replace the antique transistors you may have now. This stage is a serious commitment because it requires removing everything inside the amplifier and reinstalling the new parts. The required soldering on the Backplanes is not easy, and some owners have the Backplane Boards assembled by someone on this forum, then the owner can install it. Lots of new wiring that resolves noise and grounding issues in the original amplifier. The icing on the cake is a Watts Abundant (Forum member) Speaker Protection Relay/Delay Board. This board provides a few second Turn-on delay to prevent THUMP and an immediate speaker disconnect at Turn-off and whenever DC is present at the amplifier outputs.
The result of the Stage 2 upgrade is an amplifier with noise and distortion levels so low they can barely be measured. Increased power (from the new Output Transistors), increased dynamic range (increased bass from the new higher value Main Capacitors, and increased treble from the tighter tolerance and higher quality components on the circuit boards). Overall cleaner, brighter sound with a full soundstage giving you the ability to hear things in your recordings that you have never heard before.
Stage 2 puts your original Phase Linear amplifier into the ranks of McIntosh, Krell, Mark Levinson, Conrad Johnson, Acoustic Research, and other high end audiophile amplifiers. You may have to get a new preamplifier...
