Start with voltage checks.  Low screen or plate voltage in audio section dramatically affects volume.  Resistors increase in value with age.  Nick Senker

Hi guys:

Picked up a Hammarlund HQ170 receiver.

Audio output is just acceptable with volume control at max position.
RF gain - also at max position - also provide just acceptable operation.

Let's start with the audio...but where?...and how?....its a L O N G way from those microvolts at the antenna connection to the watts at my speaker.

(All tubes tested good in tube tester).

Tnx,
Steve
