Ansco 130. 1+6. Worked very well, but I only processed 20 or so sheets of Delta 100, so my experience is limited. I achieved normal contrast easily, and the negatives printed without problems at Grades 2 once I had it reasonably dialed in. I remember good shadow detail and nice local contrast.
I know Kodak used to publish Dektol as a universal paper/film developer. 1+9 or so is probably a good starting point.
That's all I know. It's very good to see you back on the forum, Ralph. I have missed you.

According to my Photo lab index, for press negatives use Dektol (D-72) diluted 1+1 for 5 mins @ 20c, no agitation, or 4 mins with agitation resulting in average contrast. For less contrast dilute 1+2, greater contrast use full strength, or adjust developing time. There is no specification of film brand or speed.
I once developed a roll of Tech Pan in Dektol stock, rating the film at 200 and processing for three minutes per Kodak's instructions. This produced interesting, very high contrast negatives, almost like line art.
I do it all the tine and have been doing so for about 10 years. I use a universal developer that is diluted 1+11 for papers and 1+49 for films. Negative contrast is normal and grain is comparable to that produced by Rodinal.

Ralph, when I started learning about masks I frequently used extremely dilute Dektol, as many people do for this application. It worked very well with large format film. I subsequently found my particular mask applications a little easier to control with a negative developer, and got better granularity also, which is helpful when making small format masks.
