[FERNSEH]

Introduced late 1959 the Stella ST1007 is a development of the earlier models ST8617U and Philips 1768U. Both models were introduced late 1957. Cabinet apart, the main difference from the 1957/8 models is the tuner unit. The original tuner uses PCC84 and PCF80 valves. In the Stella the RF amplifier is a PCC89.
Noteworthy in the Stella is the position of the front controls, on the left of the CRT. I think it is an attractive set, got a continental look about it.

Before any serious work can commence on this set the line output transformer windings must be warmed up in order to drive out any moisture. Usual procedure, connect the bench power supply unit to the overwind and the top cap connection of the PL36. Supply between 20 to 30 volts.

Information for the Stella ST1007U and the 21" ST1001 can be found in the 1960/61 Radio and Television servicing book. Pages 613 through to 621.
