They'd be more or less the same, I'd think. Probably an idler-wheel turntable drive and crystal pickup -- in both cases you may need to do some servicing. Idler wheel drives develop a thump when the rubber tire on the idler wheel hardens with age when left in one position for a long time, and the crystals in the pickups have a way of disintegrating if the unit has been stored in a humid location. Both situations are easy enough to deal with -- replacement idler wheels are available from various dealers, and West-Tech Services does an excellent job rebuilding crystal pickups. Webster changers were commonly installed as original equipment in mid-priced console radios in the late forties and early fifties. Like all changers of the time they could be rough on records if they got out of adjustment.
