Why D getters?

[pengboon]

I observe many times that D getter tubes being priced higher than halo getters, is there any benefit to a D getter or is it just more rare?

thanks!!

Collector mentality. Bad here, worse in much of Asia.

"Make sure it's the D-ring with the TWO welds- the three weld ones are all junk!"

Seriously, by the time you get the tube, the structure used to blast the getter is totally nonfunctional. The getter itself is the silvery stuff coating the inside of the glass.

'D' getter tubes are mostly 1950s tubes. They are more rare & tubes are priced by supply & demand. A 'D' getter does not necessarily sound better over ring type getters.

I'm glad to hear (read) this.

The only sensible reason for people to talk about getter holders is that "brand X of tube #xx# that we think sounds really good happened to be made with D shaped getters. Brand Y, with round getters, don't sound quite as good". As someone trying to eyeball the guts of a tube thru the glass can't really see much other than the outside surface of the plate. Getter shapes are roughly equivalent to the date codes stamped on the glass. If someone said "These tubes sound better because they have the datecode xxxx stamped on the glass" you'd know that they were crazy or goofed up their use of the English language. As if the same tube would sound different if they stamped another date code yyyy on it... getter shapes are in the same class as this. Like if your favorite band's music would sound any different if the name of the band was different.
