Description:
The TUBE-TECH EQ 1A is a full range one channel unit, featuring low and high cut filters with

The cut filters are designed around unity gain tube amplifiers (cathode follower) and the
shelving and the bell filters are designed around two tube operational amplifiers.
All seven sections have a separate in/out switch.
An all bypass switch is also provided.
The unit is all tube based except for the power supply.

All DC voltages are stabilized, except the anode voltage for the output stage.
The TUBE-TECH EQ 1AM has the same features as the EQ 1A and in addition, all pots on the
front panel has been substituted with 12 positions rotary switches, to give better precision and
repeatable settings.
