[R-390] Audio Chassis mysteries

[chacuff]

That's Rear Tied 5" Kielbasa in a #10 casing.  (RT-510)  Sometimes referred 
to as a 3TF7. (a common sub that's Kosher) Keeps everything working within 
spec as the voltage varies...  Generates a nice odor in a boatanchor.  Any 
oil it generates works good to lubricate the gear train as well....

Back in hiding now...
