Amplifier for Tannoy Turnberry GR

No circuit boards :)

Hi Charles1dad,

My recent negative experience with the sound of both the 275 and a big solid state McIntosh amp can be the result of an indifferent setup. I heard them at a non-McIntosh dealer that has take stuff in trade for other gear and so they amps were inserted into a system without much of an attempt to optimize the setup. Still, a lot of other amps have been dropped into this system with quite good results, so I remain wary of the sound of McIntosh gear (I have not liked the sound of their gear at CES and other shows too).

The "How it is Made" video, I think, speaks for itself. It is, to me, particularly cynical to allow the filming as a means of promoting the product when what is shown is really disappointing to anyone with even modest understanding of gear. It goes to show that they primarily market their gear to those who have no idea about quality gear. Just take a look for yourself, I know that you are knowledgeable about tube gear:

Larryi can you explain more to those of use not familiar with "how it's made" why it's disappointing to anyone with even a modest of understanding of gear? Looked very good to me.

McIntosh was known for its output transformers which had interleaved windings and insulation between each layer of winding, this was NOT something that could be spun like a top and wound in seconds, as shown in the video. Slow hand winding is also done to prevent excessive stress on the wire in the winding process.

The printed circuit board on the back panel that is used to make the connections to the input jacks and the speaker terminals is not the way to go to make good connections; I would want connections to be wired and soldered.

Larryi,
I wonder when MAC made this manufacturing change? I am Really surprised by the use of circuit board traces for input and speaker connectors. You're right, output transformer quality was historically a strength of this brand.
