Being the owner of Cart’, makes one the better judge of whether the Cart’ is a fit for the purpose Donor Model. I have took punts on Cart’s 20 Years Old and a little newer, where the Third Party Service Inspection has discovered the model sent is a Cart’ that is able to be worked on.
Worked on Cart’s have been compared to same model designs with low hours use in original condition, and the worked on Cart’s have shone as much more attractive in use.
Dampers do lose properties from when first put into a Cart’ especially over the period of years. Also Dampers wear, Light and Oxygen will degrade it. Ozone exposure eats the rubber, where it can look like a Parasite has been living off it.
The Good News is Rubber Compounds have come on leaps and bounds, there are today really high quality rubber ideal for damper duties. A New Damper supplied and Wire Tensioning produced to the Cart’ Tech’s preferences, will be a solution for producing a Cart’ that has the potential to really impress.
Read the endless accounts of the best I have ever heard it, following a listen to and follow up report on a returned Cart'.
I calculate from what I know, $450ish should be the ball park in costs and shipping either way.
