Today, I received in the mail, a vintage Teac EQA-10 EQ in excellent condition that I purchase on ebay for a very fair price. Everything works perfectly and it looks great.

I had been using a vintage Technics 8 band EQ. However, it did not really have the most usefull lower freq bands that I needed for my sys.
So, I fugured I would try the Teac.

I just have some preliminary settings but, so far I quite like it.
For one thing, the Teac seems more "musical"........less distortion?

I bought a landscape garden designer's services at a charity auction (in aid of the McMillan Nurses).

I also bought a masterclass in seafood , but got propositioned by the lady who organised the event and sold it back to her. Silly me, I think I upset my ladyfriend.

And I got two portable tool nicad packs through Freecycle, for a total of 32 1300 mA-H sub-C cells. I guess they'll be usable for bike lighting, though I'd hoped for higher capacity.
You will probably find that one or possibly more of the cells are defective. Testing each C Cell individually will almost certainly give you a boxfull of useable cells.

I bought three 14V NiMH packs and there were a total of four duff cells which rendered the packs useless.

I opened up one pack, and several of the cells looked like they were leaking. And there was no temperature sensor in the pack; the terminal is there but unused. I also weighed the pack, and found that the F-sized cells I've been using are much more efficient in terms of watts/pound.

As for new AWDWBT?, I found a pair of 4x6 2-way Kenwood car speakers (with dome tweeters) at the Salvation Army for $4; just what I need for a compact boom box system.

And Sears had this Craftsman 3-drawer intermediate tool cabinet on sale ($100 off), which will provide a place for handheld meters, tools, and no doubt random stuff that will accumulate there by osmosis or sedimentation. I've got a week to figure out how to bring it home on a bicycle... borrow a hand truck or rent a bike trailer are the most sensible options.

Well, it was going cheap.
Now I can quickly dial in any crossover point I like.

There is one thing that's confused me, though: the subwoofer low pass sets off at 10Hz, the next step being 15Hz, then 40, 75, 145, and 215 Hz.

Seems odd to have XO points so low - I wouldn't expect anyone to bother crossing at 15Hz...

Chris

could the 10Hz and 15Hz be high pass filters to help protect the bass driver?

The 10Hz to 215Hz control is on a single rotary knob.

Very odd.

The 25Hz low-cut filters on each channel are very useful - that's about where my subwoofers give up, so at least now they've got protection. The phase invert is a useful feature, too.

PS - there are, I suspect, modifications available for such a device. Sounds good to me as it is - no noise, and no departure from my home-made crossover (using TL072s and generally half-decent stuff), so I'm a happy person. This'll be handy for future projects, too. Got something in the pipeline that'll be shared as and when.
