The Visaton transformer has arrived, I hope it will work I'm not shure about the quality as it is a line transformer used in PA installations.

The transformer seems to be made as a mains transformer not EI with air gap configuration like an audio transformer, I have run a simple test, from ~3kHz to 20kHz and it has a resonable frequency response.

The guys at Sowter can make a much better transformer, but it will be very expensive.

I also have done some cleaning and resoldering, a kind of remake using PTFE sleeves.

As one can see the chokes connected to tube sockets and the feedthrough capacitors is not a good idea, I will mount the feedtrough caps so I can take the assy' out as a package.

The pictures are from my workshop and shows the Ionofane parts in a box, the other pictures shows original power supply and my project to restore the power supply with used and new parts.

The original transformer is an autotransformer, I have replaced it with a Tandberg 220V primary transformer with secondary windings for AC 300V and AC 6.3V just to make it more reliable.

So now I'm waiting for a modulation transformer, this small transformer should fit in the box together with the parts as shows in the picture.

My intentions is to make this product as near original as possible without spending too much money.
