T836/837 General Information
C1.3
The photograph in Figure 1.1 on the next
page will help you to identify the main
circuit blocks in the T836.
There is a similar photograph in Figure
4.4 which shows the main tuning and
adjustment controls.
Extending both these fold-outs will
allow you to refer to both photographs
while using the manual.
The photograph in Figure 1.2 on the next
page shows the T836 front panel controls.
