Any interest in *new* 16AP4's?
I just found out that RACS may be able to build brand new 16AP4's, but need to see if there's any interest out there.
Here's the skinny: RACS does radar tubes for the military, but these have a special phosphor on them. Since they are the same metal shell tube having the same dimensions as a 16AP4, I asked if they could put P4 phospor in them. The answer is yes, not only that they have brand new ones ready for building (about 6). The electron gun would be straight (so no ion trap), and the tube would be aluminized. If you would be interested, reply here and state the amount you'd be willing to pay for such an item. RACS is closing soon and whatever isn't used will be recycled, so it only makes sense to make use of what we can before that time.

Is RACS the source of the radar display P-7 tubes for the Moscow airport?

I'd be interested in one if the cost was reasonable but I doubt if it will be with the shipping and all.

A 16GP4 is a 70 degree tube. I would be interested in a 16AP4 which is a 50 degree tube.
Do they have any shells? Otherwise I have a couple of duds. Question: the HV (EHT) of the late 40's sets using a 16AP4 is only 10 to 12 kV. Will the aluminized screen be as bright? Perhaps brighter? Thanks, Terry

I think you have that backwards, the 16AP4 is much longer than the 16GP4 22 inches vs 17 inches for the GP4

A little text editing will avoid further confusion.

I would be interested in what RACS would price an "new" 16GP4 at. Shipping costs are going to really up the cost.

Since I have a couple of KCS-47's, I would be open to try adapting a 16G instead of a 16A. Willing to try, what with all that tinkerin' that would be needed. I'd be interested, at a reasonable price...

Regarding price, I have no idea how to answer that either, so I would go along with other comments here, "my interest depends on the cost". If they could make them at "X" cost, then I would like to know a price that is fair and profitable to the company, and that is for RACS to determine. If it is reasonable to collectors, we will want to make orders. If it is beyond the budgets of most, then there would be no sales anyway because the company would not want to operate at a loss obviously. The last "new" CRT I bought was a 3KP4 that was made in 1981, by Richardson Electronics if I remember right.

I tried to edit the title and it did save, but now I see it will not change? I alerted the mods, maybe something will change later.
This is for a 16AP4. RACS want to know what the community is willing to pay, so they can make a decision. Bouncing the ball back in their court is only likely to drive the price up, and your likelyhood of actually getting one down. So start throwing prices out. If $250 is reasonable, say so. If it's too much, say it's too much. I need a ballpark figure.

I almost had Clinton Electronics rebuild a 16GP4 years back, for $350. That
would have included new phosphor & aluminized. "No charge" in event of failure. But then the new owners said "hell no" to metal tubes, plus the price sky-rocketed on rebuilds.
