Smashup Voltage [resolved]

[1026mind]

now I don't know if you noticed but I don't have the pots nor the attenuators at the input, I'm just using the volume from my OPPO player.
could that be the reason for the little buzz/noise?

What is at the input of the pre? Just jacks wired to the grids of the 4P1L?

 

[1026mind]

yes

 

[Paul Birkeland]

You should have a 47K resistor from grid to ground on each 4P1L.  If you pull the RCA cables, the grid has no ground reference and that can cause damage to the 4P1Ls.

when I purchased the smashup upgrade I got the smash quiet to. I want to built it but I have do diagram. Is it possible to get one?
Thank you! Btw I'm waiting on the attenuators, they are in the mail from France

 

[Paul Birkeland]

I'm not certain I made one for the Smash-up.  When I have built it into other stuff, I just mount the attenuators and terminal strips on the plate we provide, then integrate that into whatever project I'm working on.
