[TenTec] TT Orion 1 flakey sub receiver

[denton sprague]

ran across something that seems to be affecting the sub receiver in my Orion 1.

If I boot the rig after I turn on its power supply, the sub receiver kicks in normally.

If I reboot the rig after leaving it connected to its power supply, which has been left on,  the sub receiver will not kick in.

If I leave the onions on/off switch in on position and use the power supply’s on/off switch to turn the rig on and off, the sub receiver performs normally. 

Orion has fresh memory battery and power distribution board cap replacements.

Also, the display wants to get a bit dim after the rig has run for an half  hour or so…and I notice it gets a little warm. Thinking of pulling the speaker and installing a 12 vdc fan in its stead to see if that has any effect.
