Teak??
Well I must ask: how are you sure it is teak? To me it doesn't look like teak at all. The color looks like bleached mahogany, or a light wood like maple, or beech with a yellowish stain or finish. Sort of like Heywood Wakefield's finishes. (But it isn't Heywood Wakefield)
Post a close up of the wood and we may be able to tell you what it is. If that really is teak, I'd be very curious to know how it was done.

Thanks Leif (by the way I...
Thanks Leif (by the way I really like your name!).
I was told by the previous owner that it's teak - you're right I was curious as to the lighter colour as well.
I can't get a pic just yet - it's stashed it in my parent's basement for now.

I'm not sure if it was just ...
I'm not sure if it was just fashionable at the time or whether it was a question of quality, but I have seen many teak pieces from the 70's in that lighter teak color.
I myself had (for a brief moment in time) a small modular bookcase from the 70's similar to a Ladderax... but not. Very similar hardware from what I can tell to yours. The quality was low, and the teak was very light. I am certain it was teak, as I had to sand a few spots and re-oil. Sanding teak stained oak or some other wood would've left light spots to restain...

Teak's not a stretch at all.
It looks very much like '70's "Scandinavian" units that were sold by the boatload here in the US and, as Solange said, often of middling quality, usually particle board construction, and almost exclusively veneered in teak.
The photo cracks me up, too. With the TV, it could have been taken in any of my high school friend's parent's basements back when I was a teenager.
Here's one of my favorite online wood species identification sites for comparing samples:

I'm almost certain that whole deal is Canadian...those knobs to me are the giveaway....perhaps by R.S Associates of Montreal..
Where are you located?

Hi everyone,
thanks for...
Hi everyone,
thanks for all your responses so far! I'm a bigger fan of the darker teak myself (love me some CADO units but they are out of my price reach for now).
tktoo - thanks for the informative site! I don't know much about different kinds of woods so this proved very helpful.
Solange - you're very observative and spot on 🙂 Located in Montreal so could very well be the R.S. Associates you mentioned.

Lighten teak
So how do you lighten teak? Treat it with wood bleach (oxalis acid)?

Two-part peroxide bleach for wood, Leif.
But why would you want to?
I suspect the lighter colored veneers like those on the cabinets above were sliced from less desirable and therefore less expensive boles.
