    A quick video on my last trip to Portugal

    WOW Mervin, lucky you are to be able to go on such a trip. What camera was used for this? Stunning quality I must say. Around 1:03, the platform at the beach used for muso's, I was thinking of something like that on our beaches. Would be brilliant to offer such a platform for local muso's to jam...

    Lockdown extended

    Yesterday my daughter told me about an article that she read on the Citizen's website, saying that drivers caught smoking could be issued a fine, should they not be able to produce the proof of purchase for the cigs prior to lockdown. Quote below and link to the site here...

    Modifying transformer voltage

    Another problem arises by just extending whats already there. And that is by how much? In order to get equal voltages one would have to start a fresh sec winding. Or, I could wind lets say ten turns over the existing sec winding, measure that voltage, then work out exactly how much turns I need...

    Modifying transformer voltage

    That would mean removing the colour wire, soldering my 1mm to the existing copper wire?

    Modifying transformer voltage

    I have some of that cloth tape stuff. Tomorrow, im going to butcher that trafo. Completely strip the sec windings and start freash. If it blows up, then it blows up  :ROFLMAO: :ROFLMAO: :popcorn:

    Modifying transformer voltage

    Spoke to a guy today, and he had something similar to say, "Hey, just wind the bloody thing" he said. Trafo as is now, is rated at 6.67 amps. So currently sitting with something like 50m of 1mm enamelled copper wire, which I bought months ago for some or other project. According to a website I...

    Modifying transformer voltage

    figured 17ac, 24/1.414. Anyway, would that be no load value?

    Modifying transformer voltage

    Amp runs at 24-0-24 dc, and at 12-0-12ac im far off from that. Its the Nico Rass Class A amplifier, labelled the RAS32.

    Thank you for that sir, much appreciated.

    Modifying transformer voltage

    I saw a design here that allowed a transformer with  dual Ac outs to be converted to a dual rail psu. So like in my case, a 0-12-0-12 to a 12-0-12. I would assume that it is just a matter of connecting two of the sec output wires together and using that as the ground or 0 volt rail, and then the...

    Modifying transformer voltage

    wire is 1m thick, and yes, will double up, one for each secondary.

    Modifying transformer voltage

    Shonver talking about adding windings on the primary. I need about 5 volts more on the secondary side. I was thinking of a few windings in series with the secondary windings, just enough to give me roughly 17 volts ac. Or does my thinking only work if its one continuous winding with various taps...

    Modifying transformer voltage

    I too would like to know what the neg is on messing with the primary.

    Modifying transformer voltage

    This would have been better https://www.bidorbuy.co.za/item/467451690/Step_Up_Boost_Converter_150W_10A_Voltage_LOCAL_STOCK.html But no dual rail. What I was thinking is, if I did just a few more windings on the existing toroidal, even if it gave me 5 volt, i could series that with one of the...

    Modifying transformer voltage

    That means I would have to strip the whole thingthen. Was just hoping to tamper with the sec windingds. Judging from what I have seen on Youtube, its about 2.7 turns for 1 volt. I dont know how the actual core would affect that. Im going to give it a try and see what happens. Maybe even just run...

    Modifying transformer voltage

    I guess it wouldnt hurt to try. Maybe just a little hurt  :giggle:

    Modifying transformer voltage

    So what you are saying is, strip a bit of the enamell, solder a set length onto it, seal with heatshrink and start winding? Would heatshrink even be okay to to join that copper wire?

    Modifying transformer voltage

    Thanx guys. Youtube makes things look so easy. Winding how ever many meters of 1mm wire through a 40mm hole was my last option. I think for now Im going to run it as is, until I can get something a bit stronger at a later stage. Would be awesome if someone would trade there 15-0-15 200VA trafo...

    Modifying transformer voltage

    Hey guys Had anybody ever changed the secondary output voltage on a toroidal transformer before? I need to get 24-0-24vdc for a little amp im busy with. Currently got a 0-12-0-12 that is only going to take me up to 17vdc. A couple of Youtube videos later and Im struggling to figure out winding...
