The HotRod Aleph Circuit Board

I'll post more pictures tomorrow of the stufing progress.

I am so used the the Mark Finnis boards these are a new learning curve.

Last night just for a lark I doubled the bias of the quassi Aleph 60 running 30vdc rails.

The most noticable effect was the hotter heatsinks and louder hum from the woofers...just a straight smoothed PS at the moment.

I have to say its sounds a sweet as honey though.

This is going to be fun..maybe we can convince Nelson to relaunch the Aleph as the Grand Daddy of Aleph with big juicy meters on the front for those freaks with low impedance loads.

Poor babies...

The next Aleph design will come out of First Watt in about a
month. It is smaller, and has no meters.

A note for future AX builders...these boards were not designed with X in mind and is not as symmetrical in copper trace design as some out there designed as X from the start. Although there are ways to balance it with the trim pot positions provided on the boards. Plus rest easy because a copper trace's resistance is much much less compared to the series resistor value in the circuit (Cu trace R<<<1% of resistor value).
 
Blues,

Are you planning the spacing for inputs or outputs from the board for terminal blocks? It sure would save alot of lifted traces when experimenting with or repairing boards. A couple of solders and unsolders and the traces start lifting, even on well made boards with good soldering and desoldering equipment. Those who choose not to use terminal blocks, they can just solder right to the board if they wish. For thoose of us that would like to use them the spacing is right. I recommend 0.295 spacing.
 
Works for me too.
peeling traces are not my kind of thing.

btw: i've been using wbt crimp sleeves on terminal blocks for nearly as long as they are produced, wbt started in 85.
wbt produces gold or silver plated crimp sleeves.
the regular set is with crimp sleeve pliers, also gold plated.
The pliers press the crimp sleeves unlike regular pliers, but the set is kind of pricy.
However, a box of those crimp sleeves costs a fraction of the entire set, and can be bought in the required size.
Maybe you know of other manufacturers who produce corrosion resistant crimp sleeves ?

(i visited wbt in Essen, only a 2 hour drive from where i live, awesome factory)

We just had Queen Mom's day a week ago, no nationalistic Orange please, i've been buying packed juice for the last couple of days. :xeye:
BowTie colors maybe, with the yellow flames ?
 
How is this for an A1.2 chassis?

Am I a good candidate? In case you are wondering....the chassis is 29 inches long by 10 high and 11 deep. I was originally going to put this together to be a straight A1.2, but now I don't know.
