Neutrik A1 service manual and schematucs

I have Neutrik A1 and A2, but now A1 is with my friend. A2 is broken. After I repaired it, it should work normally now. One of the faults is that the power supply has no power output. The reason is that a tantalum capacitor is broken and it is short-circuited. Hope it helps you.

NEUTRIK A2

I have the A2 for many years.
It displays now during calibration a message: Cal. source filters GAIN 02 HIGH.
Any ideas?
I noticed also that using W&F test and selecting IEC/DIN and 3000Hz I performed a test. I switched off the A2. Then I turned it on and selected W&F the frequency is at 3150Hz not at 3000Hz it didn't save may previous setting.
Is this normal or something is wrong with the memory?
Any help will be very appreciated?

Regards,
John.
