U.S. Telephone Set TA-1/PT with Case - MILITARY SURPLUS

The TA-1/PT is the successor of the EE-108 and TP-3 sound powered telephones. It was introduced into service in the mid 50ies and has been used by different NATO forces. The one presented here was in use in Norway.

The device is very lightweight but still sturdy. The instrument can be used on point to point connections with other sound powered or local battery instruments, or also connected to a local battery switchboard. It is specified for connections with up to 10dB attenuation, up to 6km on typical field wire.

It includes a generator to generate a ring signal of about 80VAC 20Hz. Incoming calls are signalled by a volume adjustable buzzer and a visual indicator.

Unique feature
The TA-1/PT features a visual call indicator which activates on incoming ring signals and is reset when pushing the P.T.T. button. The visual call indicator enables to switch off the ringer buzzer and still get a completely quiet incoming call indication.
