audio transformator 1:50 Amplimo

[Geoneer]

Hey you all!

I've got two 1:50 Amplimo tranformators from somebody. There is also a HV bias unit from Audiostatic with it.

But I think this 1:50 will not really drive a full range ESL.....

What do you think?

This is the transformator:

1:50 step-up trafo voor ESL's

Full power frequency starts @ 50 Hz 1.4*35=50Hz. 50W @4 Ohm equals 14 V RMS thus 700 V RMS Secondary. However @ 100 Hz it will provide 1400 V RMS and 3000 V RMS @ 200 Hz and so on till the insulation breakdown. The latter is not stated in datasheet though. Whether or not it will do for full range really depends on stator spacing.

I believe the lower 1:50 step up ratio of this ESL transformer is more suited for larger size panel with a 1nF to 2.5nF capacitance.

The frequency range at load with a 2.5nF panel will run up to 30KHz with a 50~100W RMS amplifier.

Here's the frequency correction circuit for this Amplimo transformer:

X83 thank you very much!

This is what I needed for the info to buildup de ESL with the trafo's. I've got also a few resistors with the complete set, so I have to find out if I can use them in a proper way, like described in the .pdf.

Thanks very much!
