My Ballsie Lite Kit has 4.99K R1-R8 Resistors - Parts List shows 2.0k?
Only reason I ask as previous one I built did have 2.0k for R1-R8 and as I wanted 1.5v out,
Russ advised that I should replace R3,R4,R7,R8 with 1.5k 0.1% .25W Metal Film resistors.

So questions:
1. Should they be 2.0K? If so I can then use 1.5k as before?
2. If something has changed and they should be 4.99k, what do I need for R3,R4,R7,R8 for 1.5v?

Many thanks in advance

They changed only for part commonality with other projects, to keep costs down. The most important aspect for these resistors is that they be well matched to keep DC-offset down.

If you want to match an existing unit, I can send you some 2K resistors.

Thanks for the quick reply Brian.

It was only that these are being used for Balanced to Single Ended conversion coming from a Buffalo32s into some power amps with an input sensitivity of 1.5v.

I presume as it stand the output is 2.0v?

How would I get this to 1.5v (for amps) or do you think it is probably not worth it?

Best wishes

Hi Brian,

Can I use 4.99K instead? as I just welded on it.

Also I don't have the R9 and R10. Is that ok? (I got it with the first batch of new buffalo DAC)
