This developer was designed for deep tankeuse with replenishment. It is best used for MF and LF films.
I love this developer! I've tested it with magnificent results. Dilute your DK-60A 1:3 and follow times for full strength D-76. This diluted developer is REUSABLE! Process 6 rolls per quart and discard. It's a very economical developer and the continuous array of tones are extraordinary! You won't be disappointed!
DK-60A is very similar to Kodak's DK-50, but has more balanced alkali and sodium sulfite than the DK-50.
DK60A is more active than DK-50, due to the increased amount of Alkali and the Sodium Sulfite as the increased amount of the sulfite yields finer grained negatives.
If you use the times for DK-50 1:1, use them. If not, use D-76 full strength developing times. If you want to replinish the diluted DK-60A, dilute your DK-60A replinisher 1:3 and use the developer as usual.
Try it! You may get addicted to this developer and you may not want to use anything else!
I hope that I have given you some very valuable information on DK-60A as newer isn't always better!

You realize that the OP posted this question more than six years ago? Still. it's very useful information. Always interesting to find out about developers I haven't come across before.
I have several cans of this in 3 1/2 gallon size. I think, the can looks as if it was made in 1957. It would be fun, but I've got XTOL that is my favorite.
Compared to Pyrocatechol only, the DK-60A doesn't mud up the highlights and gives an excellent tonal range when printing or scanning. The DK-60A is highly economical when using it in this fashion.
