Hoping someone might be able to help me get off the starting block with this project, please?
I’m having a hard time trying to align the BOM’s with the schematics and the photos I see on the first page of this build thread. Admittedly, the photos on page one may include added modifications that are irrelevant initially, but I digress…. My goal is to get a basic build working first. Mods later…
The BOM’s and schematics I’m referencing here are downloaded from page one of this thread…
Orange 86 AuxPWR-BOM.2020b.xlsx
Orange 86 Preamp BOM.2020b.xlsx
Orang86schematics.pdf ( from O86_Build Docs-v1.6 )
For example, but not inclusive…
Looking at the P48 Relay & Filament PSU PCB schematic (page 7), and comparing that against the Orange 86 AuxPWR-BOM.2020b.xlsx, on sheet 1 of the BOM, the BOM includes R1 and R2 which is also shown on the schematic, but there is no BOM reference for R10, R3, R4. The photo on page one of this thread shows the P48 Relay & Filament PSU PCB with placed components R1, R2, R3, R4, & R10.
The page one photos also show a jumper in place of C11, but cannot find any references to jump C11 on a schematic, a BOM or in the directions. Page one photos also show no placed components for R12 or D7. There’s also no V1 or V2 on the BOM, but placed components in the picture to name just a few.
On the Red Preamp board, the Orange 86 Preamp BOM.2020b.xlsx doesn’t have a C2 that appears to be associated with the preamp board, but again the photo on page one shows a component placement and the Orang86schematics.pdf (page 1) does indicate a C2 – 470uF/16v?
I don’t usually have to struggle with my builds when starting up like this, so I’m concerned that I’m missing something critical. I’m sure this all makes sense once it’s all figured out, but I can’t see where the documents 100% align with the schematics and the PCB’s – in particular the P48 Relay & Filament PSU & the red preamp boards. I think I have all of the off-board PCB’s placed and soldered with good confidence. Do I leave off the PCB’s anything not included in the BOM’s? Are the photos on the first page of this thread irrelevant for visual confirmation and should be ignored – at least for a basic, not modified build? Are there any photos of the PCB's and / or enclosures of finished basic builds available that I can download or view for reference?
In advance, any insight or path to follow that can be offered here would be appreciated from those who have successfully made a build. Hopefully, I’m just being dense here.
