Relative for Ideal that is.

Your a cock then
I have just paid £180+VAT+installation (awaiting final bill) for this piece of badly designed kit. My boiler is 5 years old.
When it comes to finally replacing the boiler, I will go for Valliant. I had one in my old house that worked from moving in to moving out ~ 22 years and I never had a problem with it.
It appears the transformer is underated as my broken one had bloomed plastic over it with over heating.
I intend to do some measurements and replace the transformer with something that can do the job and not some Chinese replacement.
Whether this is legal is another issue. Having something overheating without taking out a fuse to me is fire hazard in my books.

This is the orange cased 174486 version.
Apologies for ressurecting an old thread, but our 5.5 year old boiler suffered the same fate last week. The transformer had shown indications of over heating and the primary winding was o/c. Its potted, so the guess is that it has a thermal fuse inside it which has popped.
I have checked the new PCB plus its transformer and both run quite cool, so I suspect the cause of the transformer over heating has to be due to shorted turns in the primary winding, due to poor manufacture, rather than it being under rated fro the job.
BV 042-0641.0 describes the actual transformer part number, but I have not been able to find one via Google. I have tried one company which repairs the PCB's, but they will not sell just the transformers only the complete refurbished PCB. Find a company able to provide a BV 042-0641.0 and it should be the correct part.
If someone locates a source, please let me know.
I have though managed to get a brand new PCB for the princely sum of £56, so all is now working, none the less, I am interested in fixing up the original PCB with a replacement transformer, as a standby.
On the old PCB the transformer is marked thus
BV 042-0641.0
Pri 230v
Sec1 10v 2.0VA
Sec2 9v 1.5VA
Sec3 9v 1.5VA
On the new, much later board (it is a new one), the transformer is similar, but of different manufacture - it is just marked
Pri 230v
Sec1 10v
Sec2 10v
Sec3 10v
A company in China called Pulse seems to supply many similar transformers, should anyone fancy generating an enquiry with them.
The correct pin out is as follows, if you include the pins which are absent, in the count and count in a U in a clock -wise or counter clockwise direction.
Pri 4-6
Sec1 1-2
Sec2 7-8
Sec3 11-12

Ideal never managed it.
Ebay have a few, I will repair my old PCB when I get a bit of time.
There are lots of new, used and refurbished PCB I know, but did you mean transformers?
Yep ordered a couple of transformers.
I cannot find them, have you got a link please?

I've got a van full of the orange PCB's all in working order Open to offers

Go on then, What kind of van is it and what's the mileage
As for the link, it was a first page hit on eBay from mijazookin. £17.99 + £5.99 P&P. No plan to sell the fixed PCB as there seems to be a reliability issue with them so it will be stashed for when the new one blows.
It does appear to be an identical replacement transformer pin for pin. Not replaced onto the old PCB but will do in slow time or when the new controller circa £230 one blows on the coldest day of 2014 like this one did this year.
Here is the item number on ebay-
321169459048
I paid £56 for a new in its box V9 controller. £24 for just the transformer seems awfully expensive. I would have expected around £8 inc delivered for such a small transformer.
