I found a Yamaha AST-A10 Active Servo Technology Amp,one flaw.To run as a flat amp it needs a AST-K01 cartridge.Does anyone know of or can point me in the right direction as to finding one.I am new to the site and in utter amazement,holy smokes what a monster of knowledge.Thank you.
These cartridges are rarer than rocking horse excrement. But as I use S1 speakers (AST-KS1), I can use the amp if you still have it and would consider selling?
