Drawing shows tube 27 (DET-AMP) having a shield? - zboltman - 08-16-2020
Philco Model 90
The drawing on the 3 tube shield shows a tube with a shield. (The DET-AMP 27 tube)
The chassis I have does not have a shield there, nor any indication there ever was one.
Do I need to obtain a shield and install one?
OK, was searching for a 2" x 4" shield and can't find one; If I need it, where might I get one???
See Pic
Part 2,
There is a vertical clip on the chassis between the tubes.
Did this hold a shield for the DET-AMP 27 tube, or what was it for?

There are different versions of 90.
Is yours the one in the drawing?
RE: Drawing shows tube 27 (DET-AMP) having a shield? - zboltman - 08-16-2020
Yes, it is exactly that one. This is the picture that was on my 3 tube shield.
Just noticed, there are three small bolt studs on the surface around that tube. (The DET-AMP 27)

That was my next question: is there a base or the signs of it being there at some point.
I guess you answered it.
The thing looks like a spring clamp. I wonder how it held the shield...or is it even for it?

This version uses a flat plate that fits in the clip between the four tubes.

Hi Steve, I might be able to fab something. Does this completely envelop the tube or what sides and or top does it cover.

I don't know what I would do if it wasn't for this site.
You are all awesome!
