RE: Don Lowe Phoenix 8
The Futaba "Green Label" 8SGAP was 256 not 512. The red labels were 512.
I bought my "Green Label" in 1984 from Steve right after they became available.
The price was the same no matter where you bought them. They were what they called
"fair traded". I had absolutely no problems with mine in a Phoenix 6 and later a Hanson Dalotel.
Although I don't fly it anymore I still have the radio.
Sorry to hear you had problems.
