The main thing for a workshop in an ex-garage is to make sure the floor slopes slightly downhill to the door to prevent rain ingress. Doesn't take much rake to be effective.

Megatron Electrostatic Headphone Amplifier
Craig Sawyers replied to kevin gilmore's topic in Do It Yourself
You might end up with a soft start into the first C to protect the rectifier - and clearly the capacitor too!. Sort of timed relay shorting a resistor between rectifier and first C once the rectifier is nice and warm and the capacitor is charged via the limiting R. Or a MOSFET or similar device instead of a relay. What transformer is needed depends on the resistance of the inductor, the ripple on the first C (~3V p-p), and other resistive losses in the rectifier and winding resistances of the transformer itself. You could lose ~40V all told. -

Are you talking about an LC filter following a tube rectifier, Kevin? -

Well candidly, fuck me. I've just dipped into this thread, and I feel the need to barf. I have never seen such a construction nightmare. Handmade dremel boards FFS. Ugh. And that was not the worst by a long chalk. When I started building amps aged 15-16 I was doing far, far better job than that nightmare. Although an early one is festering in the attic for decades I'll wager it would still power up fine. Bit of a labor of love Kevin to rebuild the horror show. -
That must have been a toasty ride!

Heartfelt condolences.

Commissioning a new PC, DELL Optiplex 7090. My son Rob came down and helped out, putting an addition 1G SSD in there, moving bookmarks across, and putting one of the spinning rust drives out the other PC in there will all the legacy files. It is physically tiny, in spite of the fact that it has an i7 processor. It even turns out it has a backup battery in the power supply. Anyway, it goes FAST! I've gone for LibreOffice to keep as far away from the Gates evil empire as possible, and eM Client email software.

Anybody notice the Latin name for the fish? Microbrachius dicki . -
Have a totally spiffing tall day, old bean.

In her day she was an incredible ratter. We had a rats nest under the shed. They set up home because our neighbour had an aviary, and the rats were after the roosting birds. I bought a rat trap - a huge back breaking sort. Baited it with chocolate and waited. Next morning, trap tripped, chocolate gone, no rat. I eventually bent the mechanism to operate on a hair trigger, if you sneezed it would trip. Next morning bait gone, trap tripped, no rat. Those buggers are clever - they must have used a stick to trip the trap. I had no idea that rats were tool users. The guy next door tried a humane trap; all he caught was a hedgehog. Then Cleo got on the case. Worked her way through the lot of them. Of course they fight back, so she'd come in really proud with tail high looking a bit battered, and outside a half eaten rat. She got all five of them. She was a quite small cat, but a scourge of rats! And voles, and mice, and birds etc etc. Many brought back alive as a trophy to try to teach the higher primate chimp owner how to kill a small animal.

Ah - gotcha. Sorry I knee jerked - I'm just kind of raw at the moment. Can't sleep tonight very well - it is 2am in the UK

Sorry - why was that a funny post, TMoney? I can assure it it was not fucking funny having a cat I've know since she was 1 year old euthanized. Not even remotely a ha ha moment.

We had to say goodbye to our old girl - 18 1/2. Until yesterday she was great, eating like a horse. And two days ago I took her to have her nails clipped. But in the last day she went downhill real quick. In the end she could hardly stand, and had even lost the will to get out of the litter tray. At the vets there was no option, and we had to make that difficult kind choice. Carole came along for moral support, because we reckoned that the end was not far off in any case. We're having her cremated, and we'll bury the ashes in the garden RIP Cleo, you were a splendid cat.

My accent has got a lot softer after several decades away from the North East. Geordie actually has a lot of words and phrases from the dark ages invaders from Denmark, Sweden and Norway (5% of my DNA is Norwegian). I'm gannin hyem for going home is exactly the same phonetically in Danish, as is bairn for child. Fell for hill or mountain is from the Norwegian fjell, and a splinter of wood in your finger in Geordie is a spelk, from Swedish spel to chop wood. It even lives on in science as the word spallation, in which a proton beam is smashed into a tunsten target to produce a neutron beam - the proton chops the neutron out.

Happy birthday!

Newcastle - that is where I'm from. How did you get on with understanding the Geordie dialect?

Ah - the Lake District. Perfect and Idyllic area. I've been up about 80 of the fells there (there are over 200 of them all told), and pre-covid we'd holiday there twice a year, and hire a cottage as a walking base. It is about 5-6 hours drive from where we are. If you plan to do some walking there, be careful. I'm a trained walk leader, and even I can get caught out!

While we're on the subject of chocolate, that is a native word in the Mexican Indian native language of Nahuatl. As is avocado and tomato. 🍅

Forgot to say - keep the chocolate McVities in the fridge. Double delicious.
