Here's an example of how an OTR show can sound if it's taken from an original master that luckily survives in good condition. It's also an example of an unreleased screw-up by Armed Forces Radio.
"Suspense" was a long-running CBS thriller series and this episode, "My Dear Niece", was originally broadcast on January 24, 1946. The story concerns an elderly woman that is held captive by a killer and features Dame May Whitty. You may also recognize Raymond Johnstone Brett Morrison, who was the voice of The Shadow over on Mutual radio, in the role of a police investigator.
This transfer was taken from an original rejected test pressing from AFRS, where the show was distributed as program 139 in the Suspense series. My guess is that the pressing was rejected because of the speed variance problem in the opening of the show. Circulating copies of this Suspense episode sound pretty bad; here's an opportunity to hear it in near hi-fi quality.
