Ribbon tweeters - anybody tried Dayton, HiVi etc
 

What are the good ribbons - including hybrids with alu/film - in the
current crop?

Various models available from Fountek, Aurum Cantus, Dayton, HiVi etc

No, actually I think he did the stereo 30 and the stereo 70?

Actually IIRC 'Leak's' first transistor amp was a design essentially nicked
from someone else. I have one in a cupboard, and it looks like poor design
and construction to me. Only have it because someone gave it to me along
with a Troughline tuner.

Slainte,

I agree. The edge connectors on some boards were of very poor quality -
not at all what you'd expect from Leak. Electrolytics were short lived too.

What was the model? I remember the Troughline tuner. I still remember the
stereo 70 as being good though even with the audium 90s and ionofanes I
eventually used it with

Relying at this point on memory, IIRC it was the 'Stereo 30'.

There was an long 'letter' in Hi Fi News some years ago which finally made
public the story of how Leak nicked the design, then threated to sue the
real designer if they ever complained or told anyone at the time. My
unreliable memory is that Jack Dindsdale was the actual designer, but that
may be wrong. Would need to find the magazine to check.

I remember the Troughline tuner.

The one I have radiates/leaks IF like a sieve and has an IF that would be
far too narrow and non-flat to give decent stereo, despite the way some
people have fitted decoders since. That said, the impressive thing is that
it still works at all - particularly as the board was buried in about a cm
of the 'fluff of ages' when I got it. Had to replace the oscillator/mixer
valve to make it work, and re-solder a few things. But it then worked.

Slainte,

Jim

If I remember correctly - but I may be wrong - the Stereo 30 was
designed by Cliff Collinson who also designed a number of Wharfedale
speakers for Gilbert Briggs (after he bought Leak) and subsequently
designed the Quad 33/303 for Peter Walker. He left and set up Castle
Acoustics with his son.

But that is from what I remember of a lecture CC gave to our radio
club nearly twenty years ago, so I could be worng.
