    SP-10 Octal Build

    Post by 008452 on Sat Aug 02, 2014 5:05 am

    I have finally begun populating the PCB and have questions:

       1. Which board position in the PS is R15L and which is R15P? It is not marked on the the PCB diagram.
       2. What is the source/part# of the front panel power light?

    I purchased the PCB/parts kit so I will be fabricating the chassis, etc., always the hard part for me. My plan is to use copper sheet and leopard wood in its construction.

    I will post pictures when completed.

    see diagram below, the R15s are labeled R15-L (for line) and R15-P (for phono),
    also the filament regulator outputs H+ and H- are labeled line (upper) and phono (lower).
    For the front panel LED, you can use an LED that comes with a resistor to be for use at 12v, or just use a 1K resistor and any LED.

    I have some Mundorf Silver caps that I would like to try as outputs in both the line and phono sections. The problem is that they are too large. Two ideas:

    1. Mount on terminal strips near the board positions, or
    2. Mount the caps vertically.

    Can anyone see any issues?

    I also have some 1uf Dynamicaps I would like to try. Is the high value an issue?

    Thanks

    personally if you wanted to try the physically large caps, I'd mount them physically as close as possible to where they go, so either vertically or just prop them up about 1/2" and wrap the leads back around underneath them. A larger value would be OK.
