TB Audio’s TB2S is a discrete operational amplifier, designed as a drop-in replacement anywhere a 2520-style DOA would normally be used. Sporting a redesigned component layout (while retaining much of the characteristic 2520 sound), the TB2S runs on +/-16VDC- making it an attractive option for budget-minded 500-series users and builders.
