Lovely job; much better than my woodbutchery.

But as the two cores are not coupled, the 25v torroid will only reduce the voltage if its under load, the voltage out of the two transformers will be very dependent on the load on the two transformers.

I don't see that; it should work fine. I did a similar thing the other way around when we had ...

The key information is OPT primary Z-X reflected by a 8 ohm load is 6,600 ohm that is the p-p impedance.

I was looking at the Mackintosh circuit and the whole feedback cathode winding is the same as the other primary winding in reverse so quite likely QII also.

The Quad II is 3ka-a and the ...

But you have a swanky Wayne & Kerr B221 bridge. In measuring capacitance, you have to balance out leakage (D), so your bridge will warn you if the capacitor is leaky. Alternatively, you could just connect the capacitor in series with a DMM on its voltage range and put 300V across the combination ...

Gosh, as long as that? Not certain about attendance, but hopeful.

I might be able to come, and if I do, I would hope to avoid picking up the tip of a Stanley knife blade in my rear tyre. I might be able to finish and bring an unusual PCL83 2W amplifier having 3.5mm stereo jack input. Happy to contribute to costs if I come.

Hello there; I believe I've seen your moniker on diyAudio?

I looked them up, wondering if the tweeters were Celection HF1300 and had been stolen for BC1s, but no, the tweeter was something else. As were the descriptions of the loudspeakers on Fleabay. Never read such claptrap in my life. I'm guessing that Fleabay sellers use AI to write the descriptions ...

Yes, but did the Lancaster spin a bowl better than yours?

Largely tosh, I'm afraid. All loudspeakers have an impedance that varies with frequency. In general, voice coil inductance causes impedance to rise with frequency, causing a lighter load on the amplifier and reducing its distortion. A crossover complicates things, but that's the general trend. The ...

Reminds me of my Chinese coil winder. It, too, was pinned off-diameter. I was amused the recent comment I saw about Land Rovers, "87% of all Land Rovers are still on the road; the other 13% made it home." I have just done some cycle maintenance. Top tip: Wear your glasses when fitting an inner tube ...

As Kenneth Williams would have said, "I knew that". But only from about ten years ago, before then, it ran. I'm still wondering about km and speedometers.

It was changed from centigrade as that conflicted with a hundredth of a gradient.

A fascinating fact of zero practical value. Thank you; I'll add it to all the others that I find interesting. My calculator has grads. Probably for the American market.

Oh dear, looks like I'm destined for the ...

That's odd, I was strictly told at school that it was degrees centigrade, not Celsius, and kelvin, very definitely not degrees kelvin. Either they were wrong at school, or it has changed in the meantime. I reserve particular ire for those who capitalise kilo.

I have heard of gingering up horses, but let's stay at the other end with culinary uses. I love the stuff. Not so sure about stem ginger, mind, although that's what's in the Border choccy biccies. Point of order: It's the watts, rather than the kelvin that characterises a Chinese kitchen. (And ...
