Cadet Scaler BOM clarity



I’m just looking for some clarity with what BOM I am using for whichever Scaler set-up I want…
I seem to remember the old version of the site being much clearer when I built a +/-5v to 1v Scaler when the board/panels first came out (for info, this old build does not have anything in U4 and I have two LM6172IN’s in place of the TL072’s - which is prob overkill going from audio to video).

So, what does the standard BOM ( on the page do? (this page:

From the matching Alternate A BOM and Alternate A Schematic this is going to go from 1v to 5v… (and is the one I want to put together at the mo).

What about Alternate B?

Thank you :slight_smile:


Check this Scaler comparison spreadsheet I made when I was deciding which scalers to build, there are 4 sheets on that book the first one is a simple table that compares components.

The differences are easy to spot if you compare the do-not-place parts (DNP).

I built 2 Scalers: 1v to -+5v and 1v to 5v


ooh, thanks for this!
I’ll have a look through it all later :+1:


Im missing an up to date (?) BOM for alternate C (+/-5V to 1V) … I have a V1.0 that i apparentluy downloaded from the old LZX site in may last year, but noticed that its missing on the github, and i someone posted about some errors in one of the other alternate boms some time ago… (can not upload files here, only images)

Theres broken links to the BOMs of different flavors several places on the interwebs… :


true I also remember that post… search for it on the fb group maybe its there


Thanks for the replies :slight_smile:
I had a look through fb and didn’t really find anything else,
however, I have found the docs via here:

(I google searched: lzx scaler cadet [Alternate A (1V to 5V) Bill of Materials (CSV) - the links are not dead ends at the LZX site, but their own copies of the old BOMs)
