Tony's latest traffo DIY build

i have about 3kgs of copper wire that i took out from your japanese iso traffo,
if you want, i can give them back to you as i do not have any use for those at this time...

Okay if you don't need them just give those to me and i will use them later on sir.

One thing about those aluminum is they can't be soldered so twisting or crimping is needed. I found another toroid power trafo with oxidized connection causing loose contact.
 
hi sir i have here a 2"CL stack to 3.25" and i am planing to utilize the available materials as of the moment a kilo of #16, 1.2 kg of #14 and 3kg of #18 can i use #14 and #18 copper for secondary to be wound separately but same voltage then have it paralleled. the result that i wanted to have was #16 for primary 1150VA and (55-0-55 8A + 55-0-55 3A) that is 55-0-55 11A? will this be advisable?
thank you very much

not a good idea....two strands of #18 is equivalent to a #15 single wire...although #12 could have been accommodated as well...

i built a traffo in the 80's using the same core are yours, i used #16 primary and #13 secondary....
 
thank you so much for the reply
i suppose to reply yesterday but unfortunately heavy rain caused us brownout till midnight
i got 1.1kg from my classmate for free.
now i will try some comment from others on last traffo i built suggesting only 1:1.5 core ratio. then 2"CL x 3" and use #17 for primary and #14 secondary 900VA @1.5 t/v for my SR200 stereo.

thanks
Godbless
 
traffo for a 13GB5 pp amp i am making....1 1/4 cl x 2 3/4 in stack.

I just finish repairing a 502 trafo. Found out that aluminyo contacts must be properly twisted or joined due to oxidation.

Sir tony wish u a happy bday! Hope to see u soon. Dami ako nakuha na tube sa baguio. 2boxes of used and brand new from an old tech given free to my brother.
 
The lams that I asked about

Here are the pics of the lams. I included a pic where I scraped off some of the coating to show the metal underneath.

The thickness is .08mm. My caliper is kind of cruddy, but it's usually fairly close.

lams

Sorry about that.... I will have to post them one at a time due to the file size limit. I had to reduce the size of them to get them to upload. I've made them about 70 percent of the original size....
