    I have a pair of these. I found them inside some weird upward firing speakers (each speaker had its own amp)

    They are not Heathkits.

    Tubes are 12ax7 (2) EL84 (2) 5Y3

    Any ideas?

    No idea but they look like nice amplifiers. I see a good size transformer and lots of filtering.

    Pics of the original speaker cabs might be helpful to ID these.

    Any numbers on the transformers? They might indicate who the manufacturer was.

    Those have potential. I second the thought of getting any numbers you can find off the output transformer.

    I'll take a look on the transformers - good idea!

    Cabs are long gone - I got these back in 1986!

    Looks like a nicely made custom amp, painted heathkit gold. Not unusual to the era when many amps were custom made for home or studio installation.
