Hi, also can you please supply the build guides for the version of the bors supplied, I have went and downloaded the available ones and for the amp control board version 6v2.3 there is no build guide 🙁 . Thanks in advance.
Hi! Amp Control Board 6 V2.3 Building Guide is the one.
Cheers,
Valery
How different is ver.1 from ver.1.3?
I have Simpelstark boards ver.1 still unpopulated.
Hi Thimios,
The main difference is OPS configuration.
The version history is the following:
- V1 like you have is the initial design with the first opamp's inputs swapped mistake;
- V1.1 is the same, having the opamp mistake corrected;
- V1.3 is the latest update with different OPS configuration (no lateral MOSFETs).
V1 is still very good as soon as you can handle the opamp inputs swapped (only one of the opamps, the other one is fine).
Cheers,
Valery
Thanks Valery,i think that is time for the soldering gun.😉Hi Thimios,

PS Any remaining adapter board for error correction?😉
Hi Valery, thanks , I found the build guide for that version, the small pcb for the temperature sensor board? Thanks again for helping.

Here's some info on the temperature board. Take note of the temperature sensor part number instructions, each board needs to have a different sensor so the control board will know what it's talking to.

Hi Thimios! I've lost my "magic" opamp adapters some time ago but today I've found them again! I will send you 4 pieces just in case (got a lot of them) in the nearest days although you will need 1 adapter per channel.
Important - Pin 1 is marked by the square pad.

I hate cutting traces.😡
Thanks Valery!
A quick question on the build guide available for download on the vzaudio site. Does the BOM parts mentioned in the guide is for channel board? Or all the parts list mentioned with the quantity for pair (stereo set) of amplifier boards?
Thanks
Thanks
Very Excited - just paid the customs charge for my boards... should be delivered saturday!! Just need to get the other components together now!!
BoM
Has anyone made a BoM in spreadsheet form for the GB please?
I have made a start from the build guides, but it is a real drag!

Do you have the same for the other boards please?
Amp Control 6, Compact Supply and DC Detection which I bought as part of the GB

Still not bought the components... I wish I could just order them from you... Unless peeps on here want to organise a group buy? I wouldn't know where to start!

Mine is coming together slowly

OK, I will check with Jeff if he's got enough components in stock to arrange some "kits". If somebody else is interested - please let us know so that we plan accordingly
