Get together

PM received. Thank you. Looking forward to seeing you all.

Is eight the most you've ever had, Mike?

At this rate you'll have to move to a bigger house to cope with the numbers!

A pity I can't be there this time - if only it had been in September while we were on our last trip down south.

A large pantechnicon filled our double garage last week with our remaining 'stuff' and I think it will be some time before our car lives under cover again. The house clearers will be getting rid of the detritus we've left behind at the end of the week and then some final repairs can be carried out so that we can get rid of the place.

I must admit that neither of us expected to be there for 43 years ...

Sorry you cant make it Terry.
I think we have had more on previous occasions, I think it was 10 on the KB Museum opening.

On Sunday the 22nd October the KB Museum will be open for friends to view.

Thanks to Crackle and Mrs Crackle for a lovely meeting. Good to see you all again.

I'll second that! Great time had by all and some interesting items brought along. I even re homed my bag of mains neons that have been lurking for far too long!
Thanks once again to Mike & Gill

As a quick post-script to this very jolly day (thanks again to Mike and Gill !) those who were there may remember Chris - Herald1360 - offering a 500V 1A power supply to someone with strong arms and empty bench space. I was the lucky winner. Chris and I heaved it into the boot of my car yesterday evening and I powered it up, for the first time in quite a while apparently, this morning. Given that there was a possibility of bangs and smoke I thought I'd better do it outside. Here it is driving two nominal 200W mains bulbs in series - actually 210W at 240V if the meters (480V, 0.88A) are accurate. It seems to work fine.

It's purely convectively cooled and all the active devices are on heatsink plates inside the rack cabinet, so it's been conservatively engineered. The regulator pass element is a bank of 2N5240s - 100W dissipation BJTs in TO3 cans. There are 54 of them, plus a few extra in what I guess are 'driver' roles ! So the thing is large - 7U high by 47.5cm deep. The substantial mains transformer also makes it heavyish - more than 35kg in total. The next challenge is to get it up the workshop stairs !

Thanks again Chris.

Wow! I think I'd leave that downstairs and remote-control it with a system of pulleys and levers

[Herald1360]

That's brilliant

A happy new home, then.

I'll toast its ongoing good behaviour with that red at the weekend!

Those bulbs look familiar- Nick-the-Dentist gave me 7 of them!

[Valvebloke]

Spot on with the bulbs Chris . Nick the dentist did indeed point me to the skip with them in.
