Note: The following applies if fitting a WG6100 Focus Assy
ie One of these
I fitted a new type focus block, from a new WG6100 flyback. The WG has 1 extra HV wire, so had to figure out what was what, as this has never been documented before as far as I know. At first I hooked it up this way (Wrong way in pic immediately below)
There was not enough focus (Which is the problem I had before with the old orig. Amplifone focus block)
Looking at the diagram . .
You see that resistor, it was recently calculated to be about 20Meg ohms or more, because it can't be measured on my digital ohmmeter (Max 20M scale), and in order to obtain an average of 6000V on the focus pin (when in the centre), and 600V on the Brightness pin, it must be 20 Meg or more.
So if you connect it like in the 2nd picture above, you're losing 1000's of volts at the focus pin, hence not enough focus.
Remember this info applies ONLY if fitting a WG6100 Focus Assy to An amplifone HV and Amplifone Flyback
On the WG6100 focus assy there is 2 wires to the top of the block
So along that same way of thinking, the WG gets the full 19.5KV, without the 20M resistor, and we are using a WG focus block, then we should be able to feed full 19.5KV into there too. So I did (Correct way here)
