That Velleman / Maplin kit looks like it has useful possibilities, pity the reg IC isn't on the same side of the board as the mounting holes, else would readily go onto a combined heatsink / mounting bracket. Just an observation Starts me thinking about extending its leads with wires so I could do t...

Correct.

Which would be a whole 100% more power than my current incarnation LOL

Interesting, so maybe lubricant dried up? Or someone else has done it up more for some reason.

The germ of an idea is finally crystallizing

aka: "300B reprieve"


Still need to make a wooden box for it though

Profound words there D The B

Oh I see it's like an inverting amp with a gain of 5 (ish)

Seems like they might be "super tweeters" ? @ 15 Ohm - if so they don't add a huge amount, not supposed to. Or try simply increasing the capacitor value?

Apparently you should occasionally retune anyway, in case anything new has appeared. By which is meant the auto channel search thingy.

So was it just seized up then?

Well, 4A minimum, low DCR (less than an ohm ideally?) and as many henries as possible for a start? How much :)? That's the $65,000 question iniit? :D For 4A wire would be 1.7mm thick or 15 SWG, though an odd size might have to be 2mm I'm guessing 12VA size ~ can be two separate windings, you can ma...

Indeed ~ HFC sells them I believe?


In what sort of positions would you use them Nick?


(no dirty jokes please )

Oh I see what you mean, yes I was hoping for a bit more than "yes thanks"

3 US dollars each? It sez on the page. Dunno about the rest, not had a reply yet

If somebody can tie down what sort of "specs" you want, I could ask my captive transformer man. If it's just a case of winding such and such a gauge of wire onto a laminated core, how many windings etc. Presumably it has to be gapped, due to the large current I think that part of it is the...
