Sansui G7000 Driver Board Flip?

[sansuilove]

On the G7000, the driver board (F-2856) is too darn close to the back chassis , that there's no way one could check voltages at the foil side
Is it possible to flip the board? I checked the voltages at the supply board and they are matched as "mirror"
Anyone tried this?

Can you post pictures of the board showing both sides? Another technique is to build a jumper with matching connectors and ribbon wire. Then you can position the board anyway you like.

I will also think of the jumper technique
Thanks

Don't even breath on the bias trimmers in that unit unless it is plugged into a DBT. Take your voltages from the component side with a slender, sharp, insulated probe.
Something like this:

Have you ever thought that the reason for you needing to measure voltages might be because you have left behind all the (conductive & corrosive) Sansui glue?

Sorry - had to say it...

The trimmers really do look shaky I will replace them with new Bourns .
Did anyone notice the 2sk109's subs I used?
Pete honestly didn't cross my mind

The board looks like it's mirrored left and right but I don't know for sure. Are you feeling lucky?

[sansuilove]

Yes

Emmmm what's the polarity of the FET01/02?
I got original 2sk109's but can't find a datasheet
And confused - how they should be mounted?
Letters facing inside the board ?

Letters to pay attention to are the ECB, if those are transistors. I just had eye surgery so my vision is not very good yet.

 

[sansuilove]

Take good for your self firstly about the eyes .

Thing is I have no idea (no datasheet) to see which lead is what
