Lots of excellent points there, John

I would just add, if I may, that there are two ‘generic’ advantages to valve amplifiers:

1. The distortion comprises mostly even harmonics
2. In overload the waveform is ‘softened’ rather than clipped.

The best-sounding transistor amplifiers are, I would suggest, the ones which best-approximate those characteristics.

From the previous discussion : The dimensions are ~5.125" X 5.125" X .375".

… so my assumption was … a finger-tip

I saw it originally on the Apple News feed, but some folks don’t like links to that: so I found the CNN page to link here.

It didn’t take me long to reject all the ‘optional’ cookies.

That looks rather stylish, Neil

I grabbed the Mission 760 pair because they were the right size for the current living room.

… The KefKit 3 pair that I built in the 70s take up a lot of space, and the bass goes lower than the room eigentones.

MichaelG.

A noble and interesting exercise, Neil ... and they presumably have sentimental value

But [ dare I mention ? ] last week, I bought a pair of Mission 760 speakers [in pretty fair condition] from the local Charity Shop for the paltry sum of £5

Sorry to disappoint you, John … but I have just tried the link on my shiny new ‘dirt cheap smartphone’ [ Alcatel 1S running Android 11 ] and everything seems fine; so I can’t understand how a problem with the website can be affecting only your tablet.

MichaelG.

Double-sided tape [as used by carpet-fitters] might do the job neatly.

… but, of course, it has zero working-time, so you would need to get positioning ‘right first time’

I have no knowledge of that, Nigel … I was mainly pointing-out that the same item might go by various names.

MichaelG.

… But did you get down to the Camel racing, Dave ?

[ several interesting topics on the way ]

Very sad, isn’t it !?!

Reverting to first principles … Has anyone worked-out why the maker felt it necessary to include the tabulation of the obvious [sixteen times table] at the bottom-right corner ?

I am posting this News item without comment:

Technology is rapidly changing our lives, and that applies to sport as much as anywhere else. For example, RoboCup is a soccer competition for autonomous robots, watched by tens of thousands of spectators. …

I would first remove the screws, clean the joint-line and apply ‘dismantling fluid’ in small quantities … allowing it to gently seep in.

Next day … I would take a nylon-faced ‘dead blow hammer’ to it : hitting radially at many points around the circumference. This should open the joint sufficiently to apply more fluid and give it another beating [et seq]

Whilst I wouldn’t dream of doubting your word on the matter, Dave … I would just mention that my experience with Autocad and a Roland plotter dates back to when Autocad was shipped on thirteen floppy disks, and we ran it on an Olivetti M24 8086 desktop PC.

The plotter skipped around [just like the ones in the HP and Roland videos] when plotting Columbia.hpgl

By your logic therefore … it appears that was already in the ‘more powerful’ sector.

Good ol’ Wikipedia puts it thus:

[quote] A metric ISO screw thread is designated by the letter M followed by the value of the nominal diameter D (the maximum thread diameter) and the pitch P, both expressed in millimetres and separated by the multiplication sign, × (e.g., M8×1.25). If the pitch is the normally used "coarse" pitch listed in ISO 261 or ISO 262, it can be omitted (e.g., M8).^[4]: 17 [/quote]

Which is a slightly convoluted way of confirming that if you just buy M4 it will [or at least should] always be coarse thread.

Thanks, Duncan

… probably best if I stick to microscopes & stuff

I would probably agree, Mark … but having seen opening question as a simple either/or choice, I responded accordingly.

The discussion broadened somewhat after that.
