    custom SP9, finally some progress

    Post by MontanaWay on Mon Mar 31, 2014 6:51 pm

    well finally the plates from FPE arrived today for my SP9-PH10 preamp.
    Still waiting on transformer, I went with a conventional unit instead of the toroid due to space limitations, and the Hammond wooden chassis, these should arrive in the next day or so.
    I have mounted the PCB's, controls & knobs.
    The knobs are old Fender style, to keep that old school look, the on/off switch too is an old Marshall style.
    I'll do some wiring tonight between the pcb's and controls. The 'on' light will be mounted on the front of the wooden chassis. And yes, I did make sure the power transistor is mounted correctly allowing for it to be on the under side of the pcb.  Very Happy 
    I also have a plate for the rear, will take and add photo's of that later.
    The anodized finish is light bronze.
    Photo's can be seen here, http://s1029.photobucket.com/user/MontanaWay/slideshow/SP9-PH10%20Preamp

    OK, here it is in the chassis. The transformer is not the right one, it should be here in a day or two.

    Is that the Hammond chassis?

    it sure is. But it is a really tight fit inside.
    Unfortunately, the next size up of this Hammond series is way too big.
    I will be talking to a buddy of mine in our local town, he is a carpenter and he's got a great wood working shop.
    I am going to have him make one very similar, but 1" wider and deeper than the Hammond, which will solve all my 'tight fit' problems!

    thanks!
    We'll be gone until the weekend, so when I get home the transformer should be in, so be able to power it up early next week!
