...make a hole, people, comin' through
Fantastic pics, as ever.
You selling all of these?
Right let's see now. In order...
3D8 (the first one). Excellent long throw on the 6½ woofer, better build quality with the "1st gens" (3D2, 3D7, 3D8, 3D9), separate motors for each deck, proper line-in. Very loud with bass to match.
The little 3D2 has a sparkling sound & the smaller 4" centre woofer does well up to a point. Careful on the EQ & it's still pretty damn loud.
3D5: stretch the 3D2 & add another woofer, another deck & 2 bands on the EQ & you're there. Very capable considering it's size & those FM presets are *so* cool. (I'd be interested in this one if you were in then UK

)
3D30: not my favourite, but sold well due to being the cheapest of the range when available. In a field of 3Ds like this it doesn't shine, but against similarly priced mid-sizers it still out-boomed most.
3D80 (or is it a 3D88?) arguably the ultimate 3D (without a CD player). Flashing lights & all sorts of toys. Twin woofers don't mean twice the bass of the 3D8, but it's still a top flight 3D.
3Ds generally have manual decks, they concentrate on boom for your buck - which is what boomers are all about for me.
However, the servo deck on the 3D9 is the best deck on any 3D & the front panel is lovely. The twin centre woofers are no JVC Hyper-Bass beater, but the smooth "grown-up" sound & unusual looks make this a good 3D choice. It also has line in with it's own gain control (not seen that anywhere else), phono-in, Dolby on the deck (only 3D with this too).
...& then we come to my personal favourite; the 3D7 (aka TRK7620). This was the very first 3D (1985-6) & one of the first boomers with an extra woofer (the first one I saw, back then). Sound is on a par with the 3D8 (i.e. as good as it gets for a 3D). This boomer lacks proper aux-in (as does the 3D2), the EQ only adjusts +/- 6dB (more usual is +/-10dB) & only a single deck, but will you just *look* at the thing. Perfect proportions, massive side grab-handles... lovely.
Also, I can personally vouch that a set of 8 D cells last absolutely ages in a 3D7, woofer on, playing tapes at high volumes.
...all IMHO, of course
