Epilog Helix 35 purchase?

[Nick Andraka]

My Epilog Radius is still chugging along fine, but is running on a 20 year old Synrad 25w tube.

I found a local Epilog Helix 35W, (~2007?) add says the tube needs to be replaced or recharged. They are asking $2000 or best offer.
Looks like they dont have anything hooked up. so not even sure what I can check out when I go to purchase/offer.

Is there a test run that can be done to check out the X-Y travel, even though the laser tube is kaput.
Will the Helix run a file from a thumb drive in the usb port?

Any idea what size tubes would work with the power supply (and fans) of the 35W Helix? Since the 35w tube needs service, I would not mind upgrading to a 40, 45 or even 50w

I did talk to Epilog, they said it is still a supported machine.

Any words of wisdom?
I am very electronic and mechanical capable,, but not familiar with the Helix

Thanks,
Nick
