GB for Salas Folded Simplistic Phono PCB

Jump to Latest
#582
IMPORTANT PLEASE READ!!!

OKAY IMPORTANT MESSAGE

It appears likely that I shipped out ~78 2SK117GR's that are of sub-par performance.

Salas and I have tested them and they don't measure exact, but work.
On the scale of the GB, this is a small amount.

All the sub-par units are marked with 2SK117 GR OK.

This will be an eye sight test.

Please inspect your 2SK117GR's for the digits on the flat part of the top.

If you have these units, private message me, and I will replace them as soon as possible.

These are likely only in your BIB mini kits, and if you bought something else, it is not likely but possible. Let me know.

I apologize for this problem, and will take care of it.

Hi

I have the boards and the components, but I have some questions.

The 2SK117's have a large spread of Idss from 2.78mA to 5.59mA, I don't have six in the 3-4mA range, it looks like I might need to use three in the 3-4mA and three in the 4-6mA ranges between the two boards, would this be OK?

I'm confused about the values of R2 & R3 in the phono stage. I will populate both Q1 and Q2, but what values to use for R2 & R3? It's not really clear in the notes.

Thanks for the help.
