I recently acquired a 1972 year model Technika V.
I'm finding the ground glass to be pretty dim.
Are more recent Technika ground glasses brighter?
Would I be able to fit one myself?
Thanks for any advice.

The current one is much brighter and is easy to fit.
Great. Thanks Bob.
Is see Linhof & Studio has these in stock. Since you ask for advice, here's my thoughts for what they are worth: There are two styles, one is "multi-format"; in addition to a grid of 1 cm squares it has outlines for 6 x 7, 6 x 9 and 6 x 12 cm. If you think you might use any of those three formats in addition to 4 x 5 then I expect you would want that one. I don't use any of those three formats and personally find their presence makes the ground glass a bit "busy." So I like the simpler version that just has the 1 cm grid.

Thanks David. The markings on the ground glass are something I was thinking about: I like as few markings as possible so I'll probaby go for the simple grid. [6x12 interests me but if I ever get a 6x12 back I can always get the correct glass for it — they're not hugely expensive.]
Try washing the GG
Most are filthy and dim
Grind does make a difference, my 1950's OE studio 4X5 Linhof has very coarse grind
but it has uses too

Whatever you try, carefully note the orientation of GG + fresnel surfaces as you remove the old to make sure they are reassembled correctly, or a focusing error can be introduced...
If you wash GG, it will wash off lines on it, but I just draw in new ones with a hard lead pencil + drawing/measuring instruments...

Years ago the GG on my 11x14 Burke & James view camera was also "dim". Took the GG out and very, very lightly scrubbed it with a very soft brush in a diluted Ivory soap solution. Rinsed it several times under the tap, and then finally a few times with distilled water. Dried it slowly using a hand held drier. I swear after doing this, the GG was X2 times brighter. Used the same posted procedure for cleaning a front surfaced telescope's mirror... Google it.
