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!

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

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

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.
