I just finished re-wiring my PPA/STEPS combo. I was never very happy with the cleanliness of my initial wiring, so I redid everything to make it cleaner, added one of AMB's epsilon 12s and a DC output jack. I wanted to make better use of the STEPS in the PPA, so I made a switchable DC output jack so the STEPS can either power the internal PPA or an external amp/device. I wired in a bi-color LED to note the power mode. Everything checked out today and I cased it back up.

There's not much else I could do with this amp - I think it's pretty much set. Of course, that just means I'll build something else or rework my Millett.

I just thought I'd share - this is one of the few crowds that would get what I was talking about.

Please post pictures. It would be cool, if you have a before and after picture.

This thread is useless without pics!!!

BradJudy,
I like your dual-color LED idea. Makes me find new uses for the triple versions! MuHuhahahah!

I'll try and get some pictures taken today. In the mean time, here's an old picture of the front (which is unchanged):

(technically it's very slightly changed since I swapped output jacks)

And here's a pic of the wiring before:

(also note this was before the installation of the Glassman buffers)

Here come the pics...

Close up on the STEPS (you can see the three-legged LED on the upper-left):

The DC output jack and power selector switch:

The new input grounding resistor. I changed the chassis grounding to the recommened configuration of grounding the AC earth ground to the chassis and then grounding the input ground to the chassis via a resistor (10ohm 10W in this case).

New input selector wiring. You can see a bit of the not-so-great soldering of the input ground wire to all of the inputs. These Cardas jacks have too much mass and are a pain to solder well - it took a while to get something solid, so I didn't worry that it wasn't too pretty.
