Definitely replace that with a proper capacitor; it looks too small for its capacitance, even before wondering what voltage is across it. 20 years is a very good life for a pump, so I think it can be excused for a capacitor failing. A little more on this: The original capacitor was 25mm in diameter...

Failed capacitors on pumps are rather common. It's because they make the capacitor too small, forcing a high voltage gradient across the dielectric, causing early demise. And the giveaway is invariably low capacitance. We had this problem with about 600 pumps, when I worked out what the problem was...

Just a quick heads-up... We have an older gshp which has been great since installation. Last week we got an LP (low pressure) alert on the ground source loop. Diagnostics showed that attempting a service mode cold start of the ground source loop pump failed. Our provider said this proved that the pu...

Bit of a bummer. Sorry to hear that Paul. I hope you can keep the symptoms under control - preventing vascular damage is obviously the key. Is this hereditary?

Bearing in mind individual LSK170s are 8 quid or so, to get a "matched quad" of 2SK170s for only 9 quid seems... too good a deal to be true. It'd be really interesting to see just how that "matched quad" actually measure... Edit: there's a fair bit on DIYAUDIO about fake Chinese ...

I’ll never forget dropping Tom to Aberystwyth in 2005. Felt like we were abandoning him in Outer Mongolia. By the second year he’d sorted out a posh apartment overlooking the marina, sharing with three girls. Didn’t seem so bad that time! Seems to have stood him in good stead (see first item): http...

Took daughter up to Leicester University yesterday, was a lot harder than i expected to actually leave her there and come home. Really nice campus at de montford, not the towering grey edifices i was expecting, id not been there when she originally went to look It's hard to dump them and return hom...

There's 'small' and then there's 'really small'...

That's definitely really really small: 006003. And 10nF too.

Terrifying that there can be 1,000 in a modern smartphone!

There's a Spott nearby that's worth a visit...

I tend to use APC/Schneider Smart-UPS UPS systems at home...

I have an older one, and SMT-750, which makes a fairly horrid noise on battery.

Bit loathe to chuck it as they are expensive, but have a listen...

an enigma indeed...

Heading north on the A1 today, blue sky, blue sea , just out of Berwick we passed a sign , left to Conundrum and then we flashed over into Scotland - makes you think, doesn't it! https://www.tripadvisor.co.uk/Attraction_Review-g504038-d3242115-Reviews-Conundrum_Farm-Berwick_upon_Tweed_Northumberlan...

My BFE65 is currently seized. The MD65 is fine. Great little lathe - had mine for about 25 years... so not as long as you... This gets weirder. Same university, same lecturers, same hall of residence, same knowledge of Southampton, both built unipivot arms at school, both had chassis made at HL Smit...

I still need to source an adequate connector. Most give an AC rating rather than DC. Is is reasonable to convert an AC rating to give a DC rating? And if so the internet tells me VDC = VAC / (root 2). I thought it was VDC = VAC / (2 x root 2) - not something I want to get wrong! DC is funny stuff -...

Just received this; We are very excited to announce that the next Audiojumble on Sunday 2nd March 2025 will be held at a new venue! The Angel Centre in Tonbridge has been our home for 27 years and has been an important part of our history but, for the reasons detailed below, we need to look to the f...
