hi guys,
I have recently acquired my second Urei La3a and i have some doubts about its performance.
The new compressor is having too much compression w/50dB selected, much more than my other la3a, and unity gain is reached with the gain knob at around 2 or 3 max. With my other comp you get same results with gain at 4-5 and peak reduction at 5-6, but with the new one you can´t go further than 2 without really smashing the signal.
I have recapped it, swapped the optos, and installed nos transistors at Q9, Q10 and Q11, but nothing has changed. Both are terminated, both have the same R14 mod, and correct bias...
Since i have no reference unit, i have compared the results of the two with the waves plugin, and my old la3a performance is more similar to the plugin than the new one.
Any clue? it´s normal to find those differences between vintage units?
Thanks in advance, any help really appreciated .
