Philco 90- not much volume
#2

1. Have you performed the alignment? Without it your gain could be really off.
2. Just in case check the Antenna input RF coil 2 for continuity, and also the primary of the coil 7 (or which is the same, plate voltage on the first 24A tube).

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
