Early RCA Victor AM portable - 8 transistors

[Snade]

Picked this up today at local Goodwill for 99 cents.

Love the look of this radio.

It's a RCA Victor, Globe Trotter, 8 transistor, model 3-RG-81. Takes 4 C batteries.

It's in great shape, but so far I can't get any sound out of it. I think the battery contacts need cleaning or one is not making contact. I'll tinker with it.

Anybody familiar with this radio ?? Early 60's ?
