Just started MPP project

Well,made it past Step 1. I'm getting -5v . . . well, -4.9v my battery is a bit low. Thanks for the tips. Think I will bask in a successful first step overnight. Tomorrow will do Step 2. I have a tendency to rush ahead without, ahem, thinking. The manual is great, as it forces one to crawl along.

Regarding PL1 and others. If I use the supplied 3-prong connectors, should the back panel face out, or in? Or does it matter? I'm thinking of polarity when connecting power cables.

The connectors are designed to fit either way round. The outer pins are electrically connected, so it won't blow anything up if you plug it in backwards.
The only one that makes a difference is the Threshold (Audio) pot. In that case, the threshold will either increase or decrease depending which way round you connect the plug.

Neat!

Here's my Mini;


I ordered SMT 4538's so my mini is a mini mini;


The TL071 + 72's are better versions of the 61 + 62's so they are fine.
Not sure about the connectors. I bought a bare board and purchased parts...

Silverdog MPP "C" kit.

Purchased this in November, and just getting around to working on the board.

In checking the parts I notice U8 (TL062) & U9 (TL061) differ from the parts list. In the kit there is a TL071 & 72. I assume that is not a problem. There was one 79L05 missing, but I had a couple on hand.
