Two smaller ones are actually chokes. I ordered one choke (250mA/10H/<60 Ohms, height <75 mm) and I got two, 250mA/10H, 95 Ohms, 81mm.
The same with PT, I ordered 500-0-500V, got 380-0-380V. Probably they just send their standard products. But, the PT is solid made, has low resistance windings (Rw prim ~ 3,8 Ohms, and Rw sec ~ 28 Ohms, giving "total" Rw reffering at the secondary, Rw = n^2 * Rw pr + Rw sec = (Us/Upr)^2 * Rw pr + Rw sec ~ 38 Ohms.
I planned one GZ34 choke-input (LC) with 1000Vct HV winding, then two LCLC filters, R & L channels, with about 400V dc output.
Now I must "rearange" all the conception, but no big deal:-)
Although I didn`t really get what I ordered, the price is good (62 Euros for the PT and 14 for the choke + tax and shipping), that I really don`t have too much complaints and can reccomend "ae-europe" for our European forum friends (if there are any:-)).
