The external speaker plug in socket may also be kaput as its resistor measured 0 ohms across the OT secondary but as normal when removed. I'll look into that later. Not sure as of yet.

I dont understand this.

NM, You have not yet identified the model of HMV so it is going to be very to offer any specific advice.

It is sometimes necessary to remove a couple of wires to get at a component which is buried under wires and components close to the chassis in a radio. But I have never had to consider removing a whole tagstrip, that would make the job 10 times more difficult and, as you say, prone to errors if you put the wires back in the wrong place.

The skills needed to cleanly remove and replace old components will come with patience and practice.  As Trevor has suggested, dismantling an old scrap radio can give you lots of practice before you start on a radio you wish to restore.

Access is very limited on this set. You'd never be able to thread capacitor wires at the far end of the "ladder" without freeing the whole thing up. It's also held by joints to valve pins or wires that disappear through holes and re-emerge. It's the hardest soldering project to date for me. I think the mind-set was to make it strong and make it last. From the service perspective, it's an unfriendly radio. I think the traditional way of doing it was wiser. In fact, other people who have personally seen the "ladder" described it as a nightmare. You can also see the odd bulge in the wax capacitors so they have to all come out.
