My PR&E Airwave 20 analog console took a lightning hit and it looks like either the OP275 driver/buffer amps are bad, or (worse) the OP176s have gone fubar. The OP275s are still available, but the OP176 ones seem to be unobtanium. I haven't been able to find a replacement yet, and am turning to those who might know where some are hiding.

Obsolete opamp replacement
- Thread starter Bill_981

If you can't find any OP176 chips on the market, try replacing with OPA134 from Texas Instruments (formerly Burr Brown). Slightly lower bandwidth amplifier, but should do fine. The spec sheet for the 134 even shows some comparisons to 176.
