GENERAL DESCRIPTION
All models are "Personal" VHF television receivers. Models
8-PT-7030, 7031, 7032 & 7034 include an adjustable stand lor
viewing at the most desirable angle which may be removed
for greater portability. Because of its compact size and light
weight the receiver may be readily moved to any location.
These receivers are designed for reception of all 12 VHF
channels. Models 8-PT-7030, 7031, 7032 & 7034 have an adjust¬
able-rod-type antenna attached to the receiver cabinet for use
in most locations. Connections are provided for use of an
external antenna in areas where conditions require its use.
The receivers although extremely compact in size, are
adapted! for ease in servicing. The chassis assembly is readily
removed from the case and provision is made for separation of
the front and rear chassis sections with the receiver still in
operation. This feature permits ready accessibility to all com¬
ponents for service purposes.
The chassis incorporates an intercarrier FM sound system
which includes a reflex sound circuit whereby the sound I-F
stage also acts as the 1st. audio amplifier. A ratio detector;
A-F-C horizontal hold; stabilized vertical hold, high gain
picture circuits and reduced hazard high voltage supply are
additional quality performance features.
