New-building of my B1 buffer

[Babowana]

I was waiting for Papa's PCB to be available, but no news yet . . .

So, I will walk my way again with my blue color pen. The board size is 180mmX120mm. I could squeeze the size a bit. I will have neither the selector nor the volume because I have another independant box having six source selectors and 100K volume attenuator.

Any comment?

Cheers,

Your hand drawn PCB's look like fun. I bought some pens and a nice big board to play with. I've just finished my first rough draft of a hand drawn Szekeres Headphone Amp PCB. I learned a few things on this and need to try again, but it should be a little easier next time. Your B1 has some aspects I had not thought of. You are making an effort to have equal length traces between some sections. I'll add that the list of things to keep in mind when laying out a PCB. I'm following your method from your "New-building of my F5" thread. Any breadcrumbs you drop along the way will be picked up.

Thanks
Jim

You have eagle eyes . . .

I like to have the super-symmetric lenth of traces between L ch and R ch about the ground point. I do not know exactly this would have any meaning. But, who knows? The devil might be existing in the small detail . . . ?

I'm going to use the computer AC adaptor for the power supply. It has the output of 19VDC 3.16A. Since the adaptor jack is too small sized for me to handle properly, I'm thinking of cutting off the plug part including the ferrite core and replacing with two pole connector which I could easily mount to the chassis.

Hmm . . . I'm also thinking of a wooden box B1 . . .

The cloth of the ferrite core has been taken off.

As they say: "GWAS", good work as usual.
JH, If you want to try a Tooleregulator with the B1, just let me know. I have a board for you (if you want it), just needs drilling
It would be nice to hear your oppinion about it, compared to the AC-adapter.

Okay, let me try it. Many thanks

By the way, let me continue with the ac adaptor. Now the ferrite core has been re-installed on the line, and the two-pole mini connetor has been attached. Ready to be used . . .
