Here is a Picture of this Isolation Transformer. It is Rated at 300VA and Weighs about 20 Pounds, Possibly More When Wrapped to Mail it. I have No Interest to Post anything on Ebay or accept PayPal. I Will accept a Postal money Order or a Personal Cheque. Want to check me out further, go to chemelec.com |

So on that MOT you've got, 1) have you added about 35-40 more turns to the primary? (so it doesn't run the core so hot and saturated) 2) what room would you have left to install a new secondary of 100+ turns? (since MOT's are cheap, that's why I'd use two: way more room for winding a secondary, and unsaturated running with untouched primaries each running cool at just 60v) The option mentioned was to leave all primaries untouched and back-to-back link 2-pairs of transformers with the big welding cable because it's bang-up quick to wind 15 turns on each (about 40 amps max on secondaries) and only one solder joint to connect the whole dang loop together. But nothing saying you can't do the same with 14 gauge and 2 MOT's (you'll get tighter regulation too) but don't kink while winding ~50-60 turns on each or you could get hot spots later on. Hey come visit Ontario, you can stop by and grab some of my spares :-+ |

The construction is intended to reduce losses due to eddy currents. The weld increases them. Merely welding it will not make it quieter. It has to be clamped tightly wen welded. I suggest you do a bit of reading on transformer construction. |

Not sure which side of Canada your on but you could try http://www.a1parts.ca/ out of Toronto or https://leeselectronic.com/en/ in Vancouver.Both supply transformers . Lee's are more generic and A1 has Hammond.Usually takes less than a week to ship to central Canada for both. |
