[size=10pt]Hi,[/size]
[size=10pt]A few years back, I purchased a pair of SR Lambda Pros, SRM-1 / MK2 Driver Unit, and SRD-X battery powered portable adaptor. All was fine for a year or so but now the left earspeaker plays much lower than the right earspeaker, maybe as much as 6dB less loud. I have swapped the SRM for the SRD-X and right and left signal inputs to track down the source of the problem. The issue always follows the left can. The problem is the Lambda Pro left earspeaker. I checked continuity between the SR Lambdas connectors; all were open circuit as it should be for capacitors. I measured the capacitance between the bias terminal and +R, -R, +L, -L and got 138pF, 210Pf, 133pF, and 117pF respectively. I've wiggled the wires at both ends were they meet the connector and cans with no sonic signatures of a broken cable.[/size]
[size=10pt]Any idea what's up? Is anybody parting out a pair of SR Lambda Pros? [/size]
[size=10pt]I have an order in for a new pair of SR-303 but wouldn't mind fixing the Lambda Pros too. If all else fails, I'll sell the Lambdas for parts. The Lambdas very good condition except the left earspeaker level.[/size]
