but this looks like it would be ideal for what i have in mind,
so once again thanks for the information and diagram,,

I would be interested in any info/advice about replacement transformers. I believe they are 100:1 ratio, but not certain of that.

Many of the Dalesford drivers sold in the U.S. market were far different than the versions sold in the U.K. The specs were far different than the Kef drivers. One example are the Fried oem 10" that used a 135 mm diameter magnet and a extended pole piece.

Dennis Jaeger was the sole U.S. importer and distributed them to the vendors.

Default For Sale 2x Shackman Dynastat MHT-85

I am the original poster of this thread and owner of the Shackman electrostatic units.
Moving home is forcing a clearout and the realisation that my DIY speaker days are sadly over.
So if anyone is interested the two drivers, plus two very tatty but working power supply/cross overs are up for sale if anyone is interested.

Ah, brings back some audio memories from the UK audio business as it was in the late seventies.

I lived in New Barnet, and I went into his shop/house once, on a Saturday lunchtime on my way back from a school orchestra rehearsal. Probably about 1979. Although I was a teenager, I had already spent a long time fixing and experimenting with numerous pieces of commercial and home made equipment. I had some understanding of what sounded good and why, and I had a good ear.

He put a violin concerto on the record player. I was amazed. It truly was a revelation. There was a violin player in the room with us.
