Vertical Tuner - sourcing

I have an old but still usable Fox T2 but the heavy coax has (I think) damaged the tuner input socket conection. The tunner does still work for the higher power (welsh) transmitter but is very intermittent for the local repeater (West) and is getting worse. I live in the lea of a hill and want the local West TV.

I am transferring the recordings to another T2 but want to try and open the tuner to diagnose the problem or replace the tuner.
I have seen the rear of a DTR 1000 and the tuner O/P's look the same, but can someone confirm what other Humax models use the same tuner and if (and where) I could possibly buy another tuner if needed?

If anyone has attempted to replace the tuner i would also be interested if they had been successful.

Thankd

Damaged how? Can you provide a decent, close-up, in-focus picture?

What are the signal strength figures for PSB1/PSB3 on both transmitters? I would suggest the problem is more likely to be with the aerial/feed rather than the T2.
 
Be aware nobody has succeeded in transplanting tuner cans, so far as I know.

The socket itself may be easier to repair, if there is visible reversible damage... if indeed that is the problem. For example: one of my aerial points is somewhat flakey, and only tunes the weaker multiplexes if I "earth" the shield by touching it.
 
Perhaps you have forgotten that you helped me out a few years ago by supplying me with a donor board with a view to replacing a damaged tuner.
Removing the tuner from the board is a far from easy task, not only are the pins soldered in, but the can itself is held on by crimped tags, which are also soldered to the ground plane with relatively large joints. Not recomended for the faint hearted, even with special tools!
I eventually managed to remove and replace the tuner only to find that the fault lay elsewhere.
I can see no way the a loose socket could be fixed as the tuners are sealed units.
 
I hadn't forgotten but I thought you were unsuccessful, and indeed you were even if you put the blame elsewhere (it's hard to be certain).

I have tightened up the centre pin in RF sockets without internal access.
 
If you consider still working in daily use 2 years after the transplant, unsuccesfu,l then maybe you have a point!

I'd agree with that! Also what does a TV report as signal level/quality from the same muliplex frequencies. If the same poor reception for English TV then it's signal related not tuner sensitivity.

I'd also be interested in exactly which two transmitters are involved and how the two aerials are combined or by what other mechanism they are received. (Wenvoe and Mendip on the same aerial is commonplace in South Wales for example).
