Model TLA-50 Tube Leveling Amplifier 13
Circuit Explanation
Circuit Explanation
The input to the TLA-50 is electronically balanced and directly
feeds the unique compression cell. The SIDE CHAIN allows
for stereo coupling or the insertion of an equalizer. Due to
the combination of tube and solid state circuitry, long term
drift of the compression circuit is minimal and tracking
between two TLA-50’s stereo linked is within.3dB.
The TLA-50 features a vacuum tube amplifier driving an elec-
tronically balanced output stage. All the signal amplification in
the audio path takes place in the tube circuit. The balanced
output drivers provide a low output impedance for driving
cables and 600Ω loads.
