Im racking up a pair of older API 550a eq modules, the fully discrete version with the two 2520s. Both modules are of the same vintage with the same vintage 2520s. Im running them at +/- 15vdc. They both function fine but the 2520s on one of the modules get very warm,(not hot though) while the other modules 2520s get just slightly warm. Im a believer in "if it aint broke dont fix it", but Id like to avoid frying those opamps. Any tips on what might be the problem and what to test for?
Thanks
