There is no phase inverter because single-ended amps invert the signal once via the output tube’s grid-cathode relationship. The cathode follower provides low impedance to drive the 6L6 grid without blocking distortion.
Searching for the is often driven by a specific failure. Here are the top three:
Look for the bridge rectifier and large electrolytic filter capacitors. This section converts AC wall power into the high-voltage DC (B+) required for the tubes.

Territorial Acknowledgement
We would like to acknowledge that we are living and working with humility and respect on the traditional territories of the First Nations peoples of British Columbia.
We specifically acknowledge and express our gratitude to the keepers of the lands of the ancestral and unceded territory of the xʷməθkʷəy̓əm (Musqueam), Skwxwú7mesh (Squamish), and səl̓ilwətaɁɬ (Tsleil-Waututh) Nations, where our main office is located.
