I recently acquired a used Rhythm Tech Alpha Conga which I had never heard of before. I'm very pleased with it's tonality and it will added to my family of mid 1980's Classic Lp's, Tumbao Series & Alex Acuna Series Gon Bops. But it is missing the bottom support ring and is cracked. Rhythm Tech has discontinued the Alpha series so they say there are no spare parts. I am hoping that someone will have a lead that will produce a support ring. Any information will be greatly appreciated.
