Dave,
To be honest as I mentioned above, the circuit sheet is taxing me greatly. Having only worked on radios, and having descriptions of components and their function,
e.g.
C20/C21 HT smoothing
C15 AF Coupling
half wave rectifying valve (V5 Mullard etc )
this has always helped me in the learning process.
This is a whole new ball game for me, guess the component, guess the location....... I know it's second nature to the TV guys and I will get there in the end but certainly thinking bitten more than I can chew at this stage as I cannot tell my derriere from my elbow.
Those other DAC90a's on the shelf waiting work suddenly look inviting
Currently following Jeffreys lead.
