Thanks bnorrish. I will use some of your parts and ideas and bring some new ones to the table. Especially thinking of adding the Panasonic 3W resistors also as an option.
Go nuts Panasonic blue vs Vishay brown
Post #68 - was that the final layout, schematic?
-R7, R8 are 500 ohm pots?
- What about R27 - what value pot?
- J1 and J2 are resistors - what values?
- For R7 pots min 1K, i prefer 2K
- R8 you can use 500 ohm pots, but value for R6 min 560 ohm
- J1 and J2 are gate stoper. You can jumpered or use resistors, wit value from 0 to 220 ohm

I see on the original schematic from Nelson that R7 is 1K. So it just makes sense for a 2K multi-turn pot.
Yes, a 2k is perfect there.
The 500ohm is a reference to the Aleph Jango, and not appropriate to the Aleph J -- my mistake.
Good catch, BTW!!
That's a good thing to make note of on the BOM - please illustrate why you are making the choices and also what other type of peices can work. This way people can learn something about parts selection, and also have alternatives in mind if their suppliers don't have the 'right' part.I usually prefer the 25 turn ones, not the flat ones which only provides 1 turn resolution.
6L6, Didiet; please check if C2 and C3 can accommodate capacitors with a lead spacing of 7.5mm.
I will be happy to send you actual measurements from the PCB once I have them in hand, Didiet can tell you the dimensions in the meantime.
BOM updated with more trimpot info.
I would like to have some input from experience DIYers out there. From an image of the PCB I can see that only the 3386K model single turn pot will match the pin arrangement. However, I see that neither Mouser nor Digi-Key have stock of that specific model. Advice will be valued. I have also attached the Bourns 3386 data sheet, so if one of you out there can have a look at that it would be very helpful.
I also tried the Vishay model 36P as specified on the PCB, and did not have luck either although it does seem that RS stock some values for the Vishay range.
