I'm not sure what could have happened in shipping, but it now does work. This weighs like 70 lbs, so its going to cost ship. The last Pic is how it was before shipped to me, and I saw a video of working flawlessly, but not does work. I've been told by several people.
It may be and should an easy fix, but I do not know anyone who will touch this. I'm not a Tech, and I don't know anything about this type of amplifier but how to tune load it use. It does power up, and the fan runs. This is wired 220v.
So I have here a very rare Alpha PA-70 bought in working condition and it was shipped to me. You fill the with distilled water, and this is vapor cooled. I know working this can do upwards of 3k. So I have no choice but to sell it.
This was owned by an elderly ham operator who passed on and kept this in super condition. After receiving it and plugging in, I'm not getting a green light up on the left no plate voltage . This is being sold as it not working for part and repair. I know the tube is very expensive and this has like a small radiator in it.
