Hi RATs!
Just open the casework and look to see if there is a coupling cap on the input
or the output. The hope that everyone follows some fine rule is noble, but,
doomed.
Yes, two caps in a row are not the best solution, but, it is hit or miss.
If you do not look in every case, you don't know.
And two good caps in a row are better than two cheap caps. Just for reference
One is all that is needed, barring some strange topology
Happy Ears!
