Dick, I have a client with the same model here in Fl. - tunes it every 6 months religiously - It has 2 DC rods underneath it. It has not varied more than 2 cents from A=440 in the 6 years I have serviced it. It's rock-solid. Try 2 DC Rods - 1 50watt and 1 25watt with an H2. Perhaps not the answer you're looking for, but this little piano is a rock for me with this set-up. -Phil Bondi(Fl)
