Identify OLD Electronic Components!

So today, i found a VERY old radio, it was the size of a cabinet!
it had;
some 2 12"s (the voice coil diameter is about 1.5")
2 horn drivers!
120v transformer, 30Vac 3 Amps, 5.5Vac 6 Amps

Anyway, i pulled some transistors (not vacuum tubes, which was what i was hoping for) out, and i need to identify them! and find the data sheet too

Thank you in advance!

Update;
The last picture, those are npn transistors with hFE of 300

Wow... The circuit board is interesting, most of the tracking, is curved...

ancient!
yeah...

looks like it was drawn

. I didn't come up with much. :(
. First pic looks like power transistors (audio out?), but nothing turned up on Google
. Second & third pics look like a transistor. No details found.
. Fourth pic looks like a 7009 9V regulator. (That looks like "274" to me)
. Fifth pic is transistors. EBC = Emitter Base Collector. No info found.
.
. You may be able to find a schematic by searching for the model number of the radio.

yes, 274... but the board i pulled the 274 out of had E B C on it, near the pads of the transistor
The E B C means...

E = Emitter
B = Base
C = Collector

. Then it may be a transistor (could be audio out, instead of the xistors in pic#1), but it was not unusual for there to be "weird" lead markings on old PCBs. . A schematic would be a BIG help.

I have no further information on this radio, how about a photo of the PCB?
. Probably won't do me much good, but it may help others. . Any model/serial/revision numbers may help. The Manufacturer's name may help.
