Default Re: PYE TT1 - First Transistor Portable UK TV

Ten volts from the bench power supply has been connected to the line oscillator and driver stage. The line oscillator circuit is working at 10Kc/s. The correct 15 volts P- P waveform is present at the collector of the line driver transistor V34, a Mullard OC23.
Without the line output stage the current drawn by this receiver is a very modest 0.5amp @ 10volts.
The circuit diagram was posted up #7 by Valveman.
