Oh that is real helpful.

What is "accumulator power transistor earphone amplifier?"

For all I know it could be a vacuum cleaner my mom forgot to clean.

I mean discussions can't go on without any clue, right?

Just a wild guess here, but accumulator in this case i think
means the pair of 12 volt lead acid batteries. Looks like
when the unit is on, it runs off the batteries, and when you
turn it off, the batteries charge.

As far as the amplifier it looks like a very simple complementary
symetry amplifier with no output caps.

Is that a bias current meter up front?

Also, it has a pushbutton snap action switch (temporary, I think) above the power switch. Mute, perhaps?

Anyway, kinda looks heavy to be portable. But it should give you plenty of listening time...

Yeah,

So accumulator means batteries huh? That makes it simpler. Yeah, I guess I shouldn't have gotten all irritable.


It ain't ugly, I thin it is pretty. My amp is the ugliest! Oh man, it's threatening! Maybe we should have an ugly amp contest. (You know? Who has the ugliest amp? And, awards would be a nice looking chasis. So we can clean up our acts
)
