Bessler 45a with analyzer probe, fresh tubes and spare NOS tube

Description

Bessler 45a with analyzer probe fresh tubes and NOS tube. Condition is "Used". Shipped with USPS Priority Mail.
I used this briefly as an experiment before discovering that it's not for me. I've had it in storage for over a year but I'm moving and don't need to keep it. I don't have a manual so I might not have been using it correctly, it seems to work correctly but I don't know for sure. It comes with the probe. I replaced the red tubes with new old stock ones that I found and used them for about a day. The red, green and focus tubes all appear to have a lot of life to them, they look new. I have one more unused NOS tube included and the two older ones that I replaced which still do work but are at the end of their life.
I will package this well. I'd like to sell it quickly.
Here are some videos showing it function.
