We are selling the hybrid kit without opamps at the moment due to OPA2604AP being unavailable while TI try to fix the overheating problem since they moved the opamp onto a new smaller silicon fab. You can run any dual fet input opamp on there up to the max voltage of the opamp used. Opamps like TL072, OPA2134, OP275 etc. If you are not using the servo feature then any bipolar input opamp like NE5532A etc can be used as well.

The JLM Hybrid is a fet input IC opamp with high current output drive transistors. It can have the output transistors set to run in Class A/B or Class A Mode. It also has on board DC Servo that can be enabled by soldering two solder pads together under the PCB. It is pin compatible with the JLM99v , 990, 992 , 993 , MM99, 2520. Sound wise in class A/B the opamp is fast and transients snap at you. In class A the top end softens down and sounds silky a bit like the 99v but with super tight low end.

Can be used in precision Mic pres, EQ gyrators, virtual earth summing stages, headphone amps, balanced in receivers and output drivers.
