I contacted Magnum Dynalab to request a replacement center tune meter for my Etude in November 2023. (Swapping meters is easy enough to do myself.) I was aware that I was asking for an old part for an old product, and I would not have been surprised if it was not available.
I was delighted to hear from them in September 2024 that a replacement meter had been found. I am so pleased with my tuner now -- it looks and works like new again.
