Are older parison programmers repairable?

If the parison programmer is faulty and it is an old model it is very likely that the manufacturer will tell you it is obsolete and unrepairable. Of course this might be true, and it might also be that this is how the manufacturer gets you to buy a new ‘box’
Phone some of the independent repairers, like us 🙂 and get a second opinion. You might even pick up a refurbished unit. If you reflect, what is the point of putting a brand new parison programmer on a 20 year old machine?
