[Hallicrafters] SX-28 Under Chassis

[Julian Bunn]

I removed the unit last night: there is a toggle switch (mounted on the
front panel) with wires that go inside the can. Inside the can is a tube
(didn't take it out to look closer), a couple of resistors and capacitor.
It's pretty tightly packed in there.

So my SX-28 in fact has *16* tubes :-)
