I'm going to be controversial, stick my head above the parapet and no doubt get it kicked but here goes.
There is no doubt the Lockfit transistor has a reputation but like the AF117, not all are found to be bad but right or wrong they all get condemned. The following posts intent is not denying what others may have experienced but only to report what I have found and experienced, in the interests of bringing a balanced view.
As you may or may not be aware I tend to repair my sets rather than restore, meaning I only do what is necessary to get the set up and running, no shot-gunning. That does not mean I leave my TV's in a poor quality state of repair, far from it as I'm too fastidious for that. It means I replace what is needed to be replaced, to get the set up and running so it gives a very good stable quality picture. This is not to say I have not found bad Lockfits because I have. However equally I have many and I mean many sets, where Lockfits are working perfectly well. I've even removed tested and refitted lockfits that continue to function well, the trick is not to pull but push equally from beneath.
In reality I've had as many T092 packages fail as Lockkit if not more. Consider my latest set the HMV 2703, all the transistor failures were T092 packages none were Lockfit. The set is still packed full of them on the IF, Video, decoder etc. Is the picture crap, is the set unstable? No Its working and working well.
If the HMV were just an isolated example then fine but its not . Walk through my collection albums on the main site and you will find not one but many sets, most if not all have Lockfit transistors installed and working fine. As I say I can only speak as I find, I'm not saying Lockfits are without fault as they clearly do have a reputation, I just wonder if like the AF117 some are good and some are bad but not all are bad.
OH and I have many NOS lockfits and don't hesitate to fit them when required.
Well there I said it, I'm a heretic burn me at the stake and let the kicking commence.
