ADDITIONAL INFORMATION
Original purchase is from VTV Amplifier on August 22, 2021 as a dual monoblock with the 1ET-400A modules. I sent this unit back to VTV Amplifier on May 7, 2022 to upgrade to the 1ET-7040SA modules.

With instruction from VTV Amplifier, I did install a standard PC jumper onto JP1 that is located on the input buffer board to increase the gain to 14db as our speakers are extremely sensitive and require the gain. If you do not need this additional gain, you can remove the jumpers.

At your request, I can provide the original proof of purchase and receipts to include the upgrade.
