HI, Howard,
THE DK-60a replenisher DK-60aTR
Water 52'C. Mix in order 750 cc
Elon (Metol) 5.0 grams
Sodium Sulfite desiccated 50.0 grams
Hydroquinone 10.0 grams
Kodalk (Sodium Metaborate) 40.0 grams
Water to make 1000 cc
Add at approx rate 30 cc per roll of film, or in deep tank add if tank drops
more than 2 inches replenish to full line.
I also would keep an eye on PH. With D-76 there has been some mention of an
increase in negative contrast as PH rises.
Kodalk Developers
DK-40 the fist in a series of Kodalk developers from Kodak was for motion
picture positive film
D-42 is a normal contrast developer for photomicrography. D-42 is missing
the K because it is formulated with Borax and Kodalk
DK-50 is a developer for roll films, professional films and plates. DK-50r
replenisher
DK-60a is Kodak's Kodalk deep tank or machine developer for Kodak roll
films
DK-60b is Kodak's Kodalk aero film developer.
D-76 is Kodak's Elon-hydroquinone Borax developer for low contrast and
maximum shadow detail on panchromatic film and plates, including motion
picture film. D-76 is missing the K because it is formulated either with
Borax or Kodalk. All thought the development time stayed the same with
regular concentrations; there is a difference as the concentrations
increased. D-76r(Kodalk) is used to replenish D-76(Kodalk).
DK-25r is a Kodalk replenisher for D-23 and D-25 developers

Question for Richard. Do you have a formula for DK-60a replenisher
some where in your treasure trove of information?
