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.😉
PS Any remaining adapter board for error correction?😉

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.

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
