    My new ST 70 has a odor I think from the Russian caps ? Amp working fine.

    Hi Jim.

    Every new ST-70 or ST-120 amp (about 75 wired amps) that I have started in the past 5 years up has had an "odor" of some sort when started up and run for the first few hours. After 10 - 50 hours the odor diminishes. It could be the paint on the transformers or the effect of current going through the resistors or capacitors .. It is almost like that new car smell that goes away in time ... Nothing to worry about ..

    My ST120 did the same thing. Its a combo of new componets,
    paint.

    It will lessen as the amp breaks in.


    Enjoy

    I had the same experience when I fired my ST-70 for the first time over the weekend. Wonderful odor. The smell is gone now and I am experiencing some degree of separation and loss. The great sounds are assisting in my recovery process. lol!

    I have had my new ST-120 that Bob sent me just after Christmas. The odor is not unpleasant and a few of my friends actually enjoyed the smell of newness. BTW... the amp sounds incredible. I am presently using a PAT5 stock preamp but have received the kit for the SP6 that looks suprisingly like an SP8 with three boards and no mute control.... Trying to build up the courage to lay it all out and start stuffing the PCB's.
