i got some trouble with my 2 lca2b's. when compression is taking place there are quite high low frequency "thumbs" at the output of the unit (both channels) when compression drops in. it was/is not possible to run the compressor without a lo cut filter patched afterwards.
yesterday i put in 2 new special selected and symetry matched v1/101 vca ecc81 tubes (50 €) from tube amp doctor to one lca2b and did a vca balance adjustment described in the manual.
after this it is the same stupid thing...
so i'm wondering ; is this a usual behavior with the lca2b? does anybody here have noticed something similar??
