HELP - Identify mystery amp

[pmarcou]

HI,
New to the forum.
Can anyone help me identfy the brand, manufacturer or approx. output of this amp from an old powered speaker?

Thanks.

it looks like a b-52 double 15 speaker plate.

if it has a UL listed symbol, what is the number?

if it has output ic's what is the part no?

Thanks for the info --- I'll look into that.
I don't think there is a UL symbol anywhere on the amp.
I'm a bit inexperienced here so I'm not sure I can identify the output IC.
