Here is an RCA Type PB-90 with a dull gunmetal finish, and a frequency response of 30 to 6,000 Hertz.
Listen to the sound of a Type PB-90 as voiced by Tom Booth.
Tom Booth reports, “Here’s the audio sample I recorded of my RCA Type PB-90 microphone. My recording setup is simple: the mic is connected to an audio chain consisting of a sE Electronics Dynamite inline amplifier, followed by a Shure X2u USB converter, which is connected to my computer. I recorded the sample using Audacity, with no EQ or compression applied. I did use the Amplify function in Audacity to bring up the level, as the Mic Gain on the Shure X2u can be a bit finicky at times. I should also mention that I had Clarence Kane at ENAK Microphone re-ribbon and re-cable my PB-90 several years ago.”
WEBMASTER’S COMMENT: Thank you, Tom. Clarence has been a big help to me over the years. Furthermore, I use an sE Electronics Dynamite preamp with all my ribbon mics. Would not want to be without it. Special thanks to you for the sound sample! —Stan Coutant
Yet another RCA Type PB-90. It went for $1,534.99 on eBay October 13, 2004.
This one showed up on eBay during August, 2005. It appears that someone removed its original finish.
This beauty is from the collection of Darrin Warner. Interesting. Darrin’s (above) is Serial No. 1612, while the one below that showed up on eBay is No. 1616.

Mr. Schrank comments: “The stand is a PB96A1. It has a half-inch thread and is adjustable with a thumb screw. It’s the only one like it I’ve ever come across. It was a disaster when I got it with plenty of rust and several holes in the base, but a little filler and some RustOleum™ do wonders.”
