Boiler is suddenly showing no signs of life, PCB fuse is fine, supply
is fine. Opened up control PCB from its plastic casing and the casing
is showing indications of the PCB mount mains transformer over heating.

The markings on the transformer suggest 2x 9v sec. 1x10v sec, but the
pins numbers marked on the tranformer were obviously simply WRONG at
manufacture. Added to that the insulation resistance between windings
is quite low at 2M Ohm, and it seems there has to be one secondary
secondary O/C.

So I have convinced myself, based on the evidence above, that the
tranformer has failed. It is marked era Punenburg, which I guess is the
manufacturer. The era is styalised, so could well be ela.

Anyone got a line on the source because I cannot find them via Google
please?

Best bet is to give Geoff a bell or mail, he's your man for that sort of
thing.

No connection apart from being a satisfied customer..

Geoff who?

It would likely cost as much to track down the transformer as fit a
recon PCB and apparently their were issues with it anyway (maybe this
transformer, reading between the lines), it seems there has been an
revised version.

It is an Icos HE18 - anyone know what the difference might be between
the Orange and black cased control PCB's please?

Geoff at cetltd.com, who has supplied me with spares for an obsolete
boiler at a good price. He's had good recommendations here from quite a
lot of people.

Hence the URL above. Geoff does a good line in refurbed boards and
whilst I suppose I could track down parts etc he's often a much better
bet...

Yes - the original black PCBs are completely unreliable and indeed it is quite a feat that yours has lasted this long. The orange (v9) PCB is its replacement and evidently much more reliable.

I seem to recall the transformer (ERA) is one of the Achilles heels of this PCB.

Don't get upset, where is the harm?
At least its not multi emails of lists like some vendors put out these
