If everyone were to contact them and constantly be looking for parts, maybe the Big Wigs in Japan will get the message that these machines are still alive and well. They told me if a certain quota is not met for a particular part, they discontinue it. so basically if orders are not placed they will discontinue. Try to buy directly from Tascam and avoid the people on e-bay who may be suggesting a part is discontinued. Call Tascam and at least try.
