@canalsiderenovation, out of interest do you have ridge ventilation too? As an aside sometimes the loft insulation can be pushed too far into the eaves and that prevents the ventilation getting up past it to the underside of the roof.

Grain soaked in whiskey, an old poachers trick for pheasant. I bet crows are sensible enough to drink in moderation mind! Or scatter raisins on the roof and cover with a sheet of glass. They'll knock themselves out trying to peck through it... ?

I don't know if each LA has it's own rules but I got the drawings for our place, extended and reroofed in the late 1980s just by asking nicely about 4 years ago. Got paper copies, foc, taken from a microfiche. Tbh the quality isn't all that. I did thereafter ask for a scanned file that I could blow up myself. Although promised over the phone it never materialised. They were hand drawn planning drawings but have all the timber and steel sizes on. They reference "supporting calculations" which I couldn't get unfortunately. Until you ask etc. Don't forget many are working from home so something like digging through microfiche archives might not be seen as a priority.

What about a owl? https://www.pigeoncontrolresourcecentre.org/html/reviews/anti-perching-plastic-owls.html (Any PhoneShop fans? ?)

Oh it's the packaging, my mistake!

Strawberry flavoured?

Some gennies can be paralleled up. Better makes like (some) Honda models allow easy synchronisation of the two. Best to have two identical models. So you have the same voltage but double the KVA.

Balance: noun 2. a situation in which different elements are equal or in the correct proportions. So you proportion the available heat according to the variables of the room; how quickly it warms up, loses heat and so on. You do this via the lockshield valves on the rads.

Screw Archimedes I say.

Be handy for spotting the Meibion Glyndŵr neighbours with burning torches...

I love when I phone the UK arm of a company with a "global presence", "Yes, we have X of them in stock!" Then that's on a 5-7 day delivery from Cincinnati. No f***ing good if I want tomorrow is it!

In the head?

No it doesn't. Stop being a c***

"Unbalanced" ??? Reminds me that Round The Horne sketch. "My Lords, Ladies and gentlemen. Master Of The Hunt, stable boys, unstable boys!"

They're better men than me! ?

Is perhaps the 0-15v transformer not a high enough voltage to start with? Then: As I read it there's a minimum voltage differential of 3V needed. I've 5Vdc out of the bridge rectifier and R1/R2 are set up to give Vout as over 12V. So a circa 7V differential. (I have btw the 317T not 317N). Thinking to sling in a 0-24V trannie and see what gives.

Credit where it's due, throughout this thread he's not been shy of showing his cock ups.

In this photo, top right, at the back is the green supply LED. That's now coming on whereas it wasn't before. That is it's coming in even with these low DC voltages. The vertical boards to the right are essentially the channel generator I think and the right hand side, around the regulator crates the 8.2vdc that goes down pin 6. The other wire for the 2 wire comms is pin 3. In my application it's just supply to A1/A2 and then 2 wires from 3 & 6. I should be measuring I think 8.2vdc across 3 & 6. I'm measuring 1vdc only. (Pins 2 & 4 not used).

Yep, I know Radwell and am aware of that option.

The two ICs in the foreground, in front of the regulator are 7612 op amps.

On both the + & - output of the unit is a chunky resistor. Both look a bit brown but both measure at 5.6 Ohm. It holds with me thinking it died as the output was shorted.

(22vac as aforementioned on the secondary, nothing connected, just applying 230vac on the bench). Transformer soldered in. Applying 230vac to A1 & A2, nothing connected to the output of the actual unit: 7vac across the secondary 5vdc direct from the bridge rectifier.

New 15VAC transformer fitted. Off load it measures nom 22VAC on the secondary. I've renewed the 4 diodes of the bridge rectifier, Cin the 1000uF cap and the voltage regulator. Applying power and measuring between Vout and ground and I'm seeing 4VDC. I calculated that should be just over 12VDC with the current values of R1 and R2. So what's pulling it all down I wonder... On the output of the unit itself I'm only seeing 1VDC...where I'm expecting around 8.2VDC. Pretty sure the output of this unit saw a prolonged short to ground which is what cooked the trannie in the first place.

The Queen's Gambit is very good.
