Tapco A-450 Head?

[shibbz]

I bought this today. Anyone know anything about this company?
It's 450 watts at 2 ohms with 4 speaker outs, and it's stupid how loud it is.
The distortion is like a concert leads but it has way more. It has as much on 3 as my concert lead on 10.
It's a darker sounding amp so far, but I've only played it for about an hour.
I think someone installed a master volume and effects loop on it as well. I'd never heard of a master volume on a solid state amp.
Sorry about all the pictures.


The effects loop and master volume.



Look at these heat sinks!

I didn't know that Tapco made guitar/bass heads.  I'm more familiar with their mixing boards.  Tapco was pretty good equipment in the late 70's early 80's.  Other than that, I don't know much about them.

That's an oldie
You can tell by the Mukilteo address
Greg Mackie (Mackie Mixers) and Martin Schneider were Technical Audio Products Company.
Late 60s early 70s I'm guessing. I went to scholl with those guys and they were a year ahead of me.
I had one of their first. It was a custom job and it got stole in '72. The one you have is an early production model, I'm guessing
Good clean power and lots of it. They had a control they labeled "Dirt" so you could make it sound like a tube amp. Later on TAPCO got bought by EV

Where it says series, does that mean if I plug into those the ohms would be added?
Like 4ohm+4ohm=8ohm as opposed to 4+4=2 in parallel?
