    SP9 / PH10 custom build

    Post by MontanaWay on Thu Apr 03, 2014 12:21 am

    Just a quick few photo's of my 'never ending' SP9 build, finally seeing the light at the end of the tunnel and it aint a train!!
    Just waiting for the transformer now, then fire her up!
    The transformer in the photo is just there for show.

    Very tidy and clean design ... I especially like the corner splines on the case, and the satin black is a real nice touch. Bonus points if it works!

    Is that the Mogami cable you used for the inputs? I got some but ended up sticking with twisted wire for my ST120 build ...

    Oh. And you forgot the IEC well ...  pirat

    thanks people. I opted out of the IEC due to space constrains, probably could have gone with it, will see.
    Yes, it is Mogami, just made the wiring so much easier.
    The transformer arrived whilst we were away for a few days, so it will go in this afternoon and fire it up!

    I have alerted the Wallace Volunteer Fire Department; they are on standby.

    Well, the woods in the Bitterroots are still pretty damp, but ya cain't never be too sure.
    I had a fire extinguisher right next to me when I lit up my M-125s.
    Keep us posted. Anxious to hear of your impending delight.

    Animals fear light-up of Montana Way's amp

    Large mushroom spotted just now from our lookouts in Lookout Pass on the Idaho-Montana border. Trust these events are not connected with the ignition of an SP-9.

    weeeeelllllll...hate to admit it, but I did screw up the transformer wiring, almost double the output voltage than what it should be....not the toroid but a 'standard' transformer.....result, no mushroom cloud, but blown voltage reg & power transistor. Replacement components are coming.
    If I had brains it would be dangerous!.....D'OH!!!!!!!!!

    I will tell the elk and buffalo it's OK to go back to Montana, then. They're messing up our newly-paved streets.

    on a completely different note though...that link you provided, the so called mass exodus of animals from Yellowstone Park...lets be realistic, if that super volcano does decide to blow, we'll be dust in a few minutes and so will everyone else within a couple of hundred miles...so why worry!!....I'd rather go out with the first bang than be left behind and fight over scraps of food and whatnot!.....the northern hemisphere will be pretty well screwed, followed by the rest of the planet not so long after!

    well I'm hoping that the replacement voltage reg and power transistor arrive today, so that I can finally get the SP9 up and running and connected to my system!
    And yes, I have changed the transformer wiring so now I will get about 260VAC......and not close to 600VAC!!??!!.....what a Schmuck!!

    NUMBER 5 IS ALIVE!!!!!!!!....there was a movie about that.....
    Well its working, sounds great, no hum, Bass & Treble work really good, even did not mix up the left & right channels!!!
    One thing I did notice, when turning the preamp off, with power amp still on and volume about half way, you can hear a hum start up, split second, then fading away as the preamp 'winds' down, any thoughts?
    I still have the temp attenuator wired up to the ST70, I will remove that tomorrow.

    Put an itty-bitty cap across your on-off switch.

    might be a wee bit of a problem, as I am only switching 'hot'.......might have to switch both, swap over to a DPDT switch.....then I can put a cap across it....

    Better yet, turn your amp off first.

    Yep. Sequence is, preamps on for a bit, then light the after-burners. Opposite sequence shutting down: amps first, then preamps. No thumps.

    yeah, I shall do that, in any case, I swapped over switches, no switching both L & N with cap across  Very Happy.....thanks for the advise!

    I get something similar using my Sansui x001 receiver as a preamp. Not sure if it's that or the DAC, but it's just a momentary buzz and then it goes quiet. No evidence of said noise during playback. Wonder if it's just the nature of the beast as the tubes look for a signal they've been getting and all of a sudden aren't. Doesn't happen all the time. I'm also thinking it could be my dbx BoomBox needs a recap. Switching that out kills the noise too.

    Great job BTW ... the best part of any build is firing it up without, like ... firing it up ...
