Hi -

I'm Rod and I will be happy to help you with this. Is this a 520 or a 520S? There is a little difference. Replacing the tubes is not hard; however, if the unit is functioning - there would be no need to replace them at this time.

Thanks,

Rod

Hi -

As I mentioned - it is not difficult to replace the tubes. If you do need to replace them. You must remember to neutralize the finals when you replace those.

Do you have a copy of the service manual? I can provide you with an electronic photo copy if you desire.

If it is properly working - I do not recommend replacing anything.

Thanks,

Rod

but do you have to neutralize the finals on the one tube on the drive?
Expert:  Rod replied 1 year ago.

Hi -

I see you just want to replace the driver - low power output?

You do not have to neutralize the output tubes if you are not replacing them. When pulling the tube out - grasp by the base and gently wiggle while pulling up.

Let me know if you need any more information.

Thanks,

Rod

Is there any alignment or does it go in only one way?
Expert:  Rod replied 1 year ago.

Hi - there is an alignment but it is by the tube pins. If you look at the base, there is a gap between the pins. That is how you align to socket.

Thanks,
