JLM’s Hybird is an opamp in the 2520/990 footprint that combines a Burr Brown FET input opamp with discrete transistors. It can be set to run in either class A or class A/B modes. According to JLM, the class A operation has a touch of the “silky,” “softened” sound of the JLM 99v, while in A/B mode it passes very fast, snappy transients.

Features:

• OPA2604AP IC opamp
• THD = 0.008%
• Can be used in place of any 2520/990-style DOA

Price: $30 for full kit
