Default Re: AVO Model 7 Restoration

Dave,

Thanks for your Compensator Data.
Very similar to mine.
I rounded up a bit, I think mine measured out at the high end of 2.4 Ohms around 2.46 as I remember, so they are pretty close.

By tweaking the Coil Mount the Max and Min can be adjusted both upwards or both downwards, hence I was interested to know where Avo would have set it to start with?

I had to remove the Coil to repair the Resistance Wire, hence it might not be exactly where
it should be, but it matches yours quite well.

When I get the old Girl back up and running, I will carry out some more detailed Temperature Checks.
The Model 7 was certainly a sophisticated piece of Kit at the time.

Does anybody know when the Temperature Compensator was dropped from the Model 7 ?


Tim,

Does your 1952 version have the Temperature Compensator do you know?
