Ok, will my RS 1500 have problems with these tapes?

I don't think it would be an issue. But with that deck, who knows. I've always been perplexed by it's circuitous, serpentine tape path. Maybe someone who uses one of those can chime in.

  The only Q I would have is the deck in question have enough bias current for 900. DRam did not mention which deck was intended for use. Some of the older decks can not put out enough bias current for 900. If that is not an issue, then would agree with the other posted comments.

    my deck is an Akai GX636. I'll have find out what the bias current is, and if it's enough.

      One indicator would be the bias table that is usually in the manual for the 636. Does this table show a bias setting for Scotch 250? This was a high bias tape back in the day. If not, then you likely won't be able to bias the deck for EMTEC 900.
      
      Go for 911, which biases up very closely to the old ampex 456.

        It does have a setting for Scotch 250. Thanks for the help.

        good. just keep in mind that a 250 bias setting does not mean you'll be able to bias up 900. It means you may have a chance. If there were no bias setting for 250, then it would mean you would have a very slim chance of being able to bias up 900. Be sure to use a tone generator. If you don't have one, there is a good available for free in the trial version of ARTA software. If you under bias, you may end up with a rising top end (upper freq) which will wear on you. Will also depend on the range of the pot used to set the record EQ if the 636 has one. If you don't have a record EQ pot, or at a given bias setting you run out of room on the pot, then forget the the 1 db of over bias, and go for flat freq response at 15K @ 7 1/2 ips. Your deck should do that. Don't forget to do a fresh head demag too before attempting the bias setting. Good luck!
