Hey guys, I have a PD-4501 #997 that I am restoring and had a question for you. In my seated bus, there are radio controls above each seat with volume wheel, installed into the parcel racks. It looks like they(Greyhound) used some old form of tube or hose type headphones. What kind of radio did greyhound use on this bus, as well as what kind of PA was used ie make and location of mounting. Anybody know?
Standing on the top deck and look out of the top front window, it looks like there was once a mounting ball for what I guess was the antenna.
I was told that only the last fifty(50)or so Scenicruisers that were made had passenger radio, and those buses would run cross country.
Any info that you might have would be great, Thanks, Aaron in Oklahoma
I had heard that it was only some of the east coast buses that had the individual passanger AM radios.
1 or 2 of mine have that ball antenna mount on the roof (none have the radios, passanger or PA), I thought it may have been for a dispatch radio.
Anyone here old enough to have ridden on a scenicruiser & listened to the AM radio - & young enough to remember? :o 8) ;D
Ours has all the radios in the bottom level as well as a PA box loose on the dash. I am looking forwad to learning more about it.
I would LOVE to see what the tubes looked like!
I just realized how really old I really am! The statement, I would like to see what the tubes look like brought home what a antique I have become! I had a Young helper years ago in a industrial environment who asked Me what the glow was in a large tube in a spot welder. It had never occurred to Me that vacuum tubes were no longer part of the electronic curriculum. Thanks for reminding Me I am over the hill, LOL. Regards john

Actually, he was talking about "Gosport" headphones, which are essentially a plastic disposable stethoscope with long tubes, which carried the sound from speakers mounted in the panel, console or whatever. These were popular for decades in airliners, until the Sony Walkman brought headphones which weren't like wearing a vise on your ears, and which were cheap enough to throw away when they break. If you ever notice two holes in the armrests, about 1/4" in diameter and 3/8" apart, that's the stereo Gosport connector.
