I ordered one last night, so I shall see what difference it makes to my line when it arrives.

The replacement Mk3 SSFP arrived this morning and so the damaged one was opened up and its PCB was photographed. The image is attached below, along with that of a Mk2 SSFP's PCB.

It's let us play "spot the difference" time.  ::)

Looks like it has more windings on the ferrite core on the MK3

Although the body colours are different, the bands designating the resistance are the same. (I see red, black, black, gold which shows them as 20 Ohm +/- 5%)

Yes, indeed. The two windings on that toroid are in series with the A & B wires of the circuit, immediately following the plug which connects to the NTE5/A.

Thats going to add a bit more attenuation to the line not by that much say 1.0 to 1.5 dB but suspect it will be higher than the MK2 which added 0.5dB to the attenuation :-\

When swapping between the mark 2 and mark 3 on an Hg612 there was no change in my over all attention or sync. pbParams showed no changes in D1 and D2 and a consistent 0.4 db increase in D3.  in U1,U2 and U3 there were some 0.1 db increases in some values but nothing significant.  With the HG612 there was nothing really significant at all.  A 1 day test suggested a smaller error rate reduction but my error rates are not really stable enough to allow a reliable judgment.

The guys at BT Harrogate are aware of the issue (as in issuing out of the stores) of the Mk3 SSFP so it is definitely legit item.

Me thinks that you intended to paw out "issue of the Mk2 SSFP", as that is the device of which the Wizards of Grimbledon Down1 were tasked to "look again". The Wizards looked, changes were made and the Mk3 SSFP is the result.

Of course the Mk3 could, in turn, be lacking!  ::)
