    LG Flatron W2241S

    Come on Letifer...dig out that old radio like 73's de Edd says....I'm curious what he is about to suggest here. Always like to learn something new. :)

    Parallel and series generator and batteries

    Depends on many aspects of the installation. Battery type ..... Regulator arrangement....monitored installation or standalone.... Wind generators in small scale invariably simply do not work. Usually due to how much wind blows ( or as in most installations, doesn't blow as expected)

    How many watts solar panel to power this Fan?

    12v x 2.6A = 31.2W ....half speed maybe 1/2 of that.

    Intercom replacement questions.

    You will need, at minimum, to post schematics of both here.

    solar panel reverse polarity protection issue

    Why would one need reverse polarity protection on a wired in device?

    9500v to 9.5v

    A spark plug will detect a correctly working fenceline.

    180vdc to 75 vdc

    Then why not just use 80v worth of the batteries..???

    Parallel and series generator and batteries

    Have to remember they usually contain some type of regulator which depends on battery potential to operate correctly. I go with Bob.

    180vdc to 75 vdc

    What is the origin of the 200v supply?

    Varnish vs enamel

    Spec says insulating varnish and at 60Kv /mm I'd say so.

    Parallel and series generator and batteries

    Parelallel 12v is still 12v.....no good for 24v.....series gen sets might give you a headache also... re. Regulation. Don't know what your reference to batteries rated at 12A means....usually they are rated at Ah.

    How to remove solder from plated-through holes?

    Tried that once but ended up with the soldering iron lead wrapped around my neck and just couldn't seem to hit the hole each rotation.:D

    How to remove solder from plated-through holes?

    Now I know some are going to have a good laugh, but in some instances, (using the right iron heat of course) I have used the workshop compressor to blow out any stubborn holes. Just keep your bare feet well clear though........:oops:

    Marine Radio Transceiver repair.

    These (2sc1971) claim to be genuine Mitsubishi....... although, of the many claims about dilutie gear from Asia being cowdung, I've never seemed to have had any problems with the stuff...

    Alternatives to lead acid in the hundreds of Ah

    Look for tesla batteries but expect to have deep pockets.

    Simple transistor / LED circuit problem

    without any bias on the base as your drawing shows, then one has to assume the transistor is kaput. Either that or you have a pnp transistor.

    Found another site with vast resources

    As above.....as a taste, checkout the section "subject index".:eek: Cheers ...Jorgo http://www.homofaciens.de/index_en.htm

    Choice of the cable for motor driver

    Have no idea why it should be shielded, however, 2.5sqmm will handle 15A ok depending on how far you intend to run the cable.

    Capacitor 1950 µF

    Epcos is a German company.

    Capacitor 1950 µF

    Sounds about right. Any cheap replacement obviously will not last.
