Two Pairs (total of 4)-Sonic Imagery Labs 995FET-Ticha Discrete OpAmp for use in a 2 channel stereo amplifier. These opamps originated from the input buffer statges of two new VTV-Purifi monoblock amps. They are in as-new condition and sound fantastic! I am upgrading to the Weiss input buffers (which are considerabley more expensive) and I no longer need this set. More detailed technical info can be found on the VTV Amplifier website.This is an excellent price for these high-grade devices. https://vtvamplifier.com/product/pair-two-sonic-imagery-labs-995fet-ticha-discrete-opamp-api-vtv-amplifier/ I ship only to the lower 48 states, and I will package and ship the same day as the order is received if USPS is open.
