Being the "winder of the pig", take it from the old hands ... you just have
to roll-up the sleeves and get a little dirty. Rummage through old
2nd-hand electronics stores.
I approached a local transformer maker & quote for 7.5 kVA core was $650
AUS !!
The 5 kVA (which I can probably run at 7.5 kVA) transformer which I
re-wound cost $100AUS (ie. about $65US). Then the primary was already wound !
As for educational ....... well, I guess I did learn a lot, but boy, I
wouldn't want to do another one for a while ;-)
As for the other "Adelaidian's" on the list, Kab's Recycling has another 4
of these transformers for sale. Get 'em while there HOT !!!
cheers,
