Mr. Jsman, several of the aforementioned tape recorders can playback the tpt's. only 2 of them lack the ability (via a simple switch) to play IEC equalized tapes-the prosumer teacs, and only ONE lacks the ability to play at 15ips. plus i could always dub the recording onto that deck turning at 7.5ips as well- i'm sure with excellent results.
the reason for 5 decks? check out the Teac A-6100 Master Recorder, which i picked up for "a song", with 4 heads and wooden side panels. or an X-2000M, a modernized version of the A-6100 with an autolocater, DBX-1, and a spooling feature. i used to have this "urge" to see what vintage machines would come up for auction- some of them are real jewels- (i.e.- the teac 35-2 had the option of connecting your recording preamps directly to the heads). BTW, none of them cost me a fraction of what i spend on high-end audio. AND, when you need parts for Teac or Tascam decks (for the newer models of course), you call or e-mail them in california, they ship them to your door.
i can afford the tapes btw. maybe one day...
