I didn't think I would be revisiting this thread, but it's possible I may be purchasing an RX-80ES. Just communicating with the seller and if it comes to fruition, I will post more details.

The moderator on that forum: How is he sure the decks being brought in for service and had accelerated head wear were from customers/clients who exclusively used Type IV cassettes? It wouldn't take much time for a number of playbacks with a few select Type II cassettes that had a coarse...
As shown on the wrapper of the Sony HF-S 90, above: for playback in personal cassette players and car stereos where those frequencies may be dampened.

@vince666: That's a good explanation. The manufacturer would sometimes display such information on the wrapper to distinguish the tape characteristics from other models within the same tape type.

Nothing wrong in not rushing it, George. This has been a great project to follow.
Yes - there is the ad that appeared in most audio magazines of the time (1978) pitting the Pioneer CT-F1000 against the Nakamichi 1000II.

Actually, it has been shown the TDK CD Power is close - if not equal - to TDK SA-X. It's likely the TDK SA-X offcuts ended up being spooled as TDK CD Power.
