Hi,
I have messed with this all last week.. Here is the problem:
I bought two jj6386 tubes for Sta-level compressor clones.Both tubes are working and compressing fine, but there is strange anomaly...When compressor compress hard and signal stops and compressor meter needle comes back to zero (control voltage decreases to 0v) there is strange and annoying noise "bump".Both tubes make it ,but bit different way.
Compressor signal amp and sidechain are 1:1 to original ,all voltages are ok,all tubes are in balance.Compressor working without any issues with so called "T-bar" ( pair of 6BA6 connected into triode mode instead 6386)
Can it be tube quality issue ?Does anyone had same problems?Is it possible to do something with this?
I know that todays tubes are not very good compared to nos but jj claims that they test and choose every 6386 ...and yes,they were not cheap.
