I get the impression it is quite big !

Give details of size, weight, VA, Vac, windings, turns or turns ratios, etc.

[TonyTecson]

Big? not really, core is a 1 1/4inch squared, core rating of about 75VA,

primary at 220volts,60hz, 950 turns of #24 magnet wire, layer wound.
secondary1 at 120volts, 0.4 amps, 570 turns of #27 magnet wire, layer wound
secondary2&3 at 6.3volts center tapped, 3.0amps, 28turns of #18 magnet wire..

update:

after painting the traffo, i had some aluminum covers made, since no end bells can be found anywhere for 2inch cores that i know of:

wow...nice build sir....it's really nice building your own trafo especially if u have those equipments....customizing trafo for you own use is really a factor and sometimes cost saving rather than buying ready made trafo that not exactly as u want...some store sell trafo of false VA rating just voltage and amperage and you dont know wether it for a single wind rating or dual...if you not familiar with the core size you can be fooled.

thanks, one reason i build my own traffos is so that i get what i want and not be limited in that sense.....

[Junm]

Sir,do you accept special orders?

[TonyTecson]

not really, still a hobby for me, but fire me an email with your requiements and i may be able to help.....

[Junm]
