<html> <body> Hi Dave,                Contact Robert at Samick he will give you the authorization to do warranty work,  He is aware of the problems. But first contact the dealer, he may be able to help. The principal problem is graphite that has been applied too thick. There was a plating issue, but not that recent. The graphite has now been dropped from all Samick action parts.  Products that have all Renner parts will have a light coat of graphite on the cloth. I would respectfully suggest, that you not refer to the instrument as a PSO, if you are looking for max cooperation. Hope this helps.

Before I could even tune this little PSO--a Samick SG 150 with a Pianomation player unit--I had to deal with what I thought was regulation issues, but turned out to be bound up centers, mostly on balanciers, but some hammers, jacks, and whippen heel flanges were also victimized. The original pins were contaminated to the point where each time I pushed one out, it was a struggle to get it to break free, and I thought the bushings were going to come out with the pins.  Fortunately, that didn't occur.  But there was a black substance coating the pins at the point where they pivoted on the flanges. I am certain that I will be called back soon.  There will be more binding centers, and I'll wager that the flange bushings will have to be replace before too long. I have a call in to Samick for possible warranty reimbursement for the customer, and I'm wondering if I should ask for a set of replacement whippens(keep dreaming, Dave). At first I thought that something had been spilled in the action, but there is no evidence of liquid contamination(other than blood from my finger from pushing too many pins through birdeyes), then I remembered the recent thread about Renner actions using graphite covered pins.  Does anyone know if Samick uses or has used these in the past?  The piano is around three years old. Mr. Jolly, you can e-mail me privately on this if you'd like:  what is the likelihood of any of the warranty reimbursements or replacements I suggested?  The customer said that it has been going on since he got the piano.   Thanks in advance, Dave Stahl </blockquote></body> </html>
