A lot of intermittent problems will prove to have a mechanical sensitivity.

Just pressing the power and/or preamp buttons lightly might reveal an oxidized contact in one or both. Your receive signal passes through both of those switches.

The relay is the next suspect when this happens. Removing the amplifiers cover and tapping the body of the relay will reveal a mechanical sensitivity there.

Just sounds like a switch or relay contact point cutting in and out.
