Aleph J for Universal Mounting Spec - Page 4

Didiet - I am waiting to get some specific answers regarding the potentiometers. Sory for the lack of communication.

Everything is looking very good so far!

Once the boards are tweaked and look good I am planning on getting a pair made locally for proof of concept and prototype.

Add trimpot for setting Output bias (R27).

That looks great!

Could you rotate the pot 90 deg and add the pads for the resistor, similar to the other pots?

Like this ?

6L6 · 13th December 2012, 01:48 PM

Yes, thank you! That is great.

A question -- I do not have much resolution when looking at the drawing, so I need to ask, ?Are the potentiometers being connected as variable resistors? I.E., with the wiper connected to one of the legs?

didiet78 · 13th December 2012, 02:07 PM

Yes, center leg connected with one leg.

nice board and good distance between the IRFP's. Would be nice to have pads to bridge to RCA. When will the board be available?
All a nice holiday season

bridge to RCA is just solder in a jumper. there is realy no need for extra pads for it

If this board is going to be offered via the DIY Audio shop, is there any chance of an option to have the elusive FETs included as a kit?
