Using the last bit of D76

[wakarimasen]

Hello Folks,
I'm using my last bit of D76 to develop an Ilford Delta 400 film in 120 format. I've only got enough D76 to make a 1+3 solution (500ml) but the spec sheet doesn't show a development time for this, and the Massive Development chart only shows a value for Iso 500. Any suggestions for standard development times - i.e no push or pulling?
Best regards,
RoyM

I thnk the dilution is not in the Ilford documentation because of the long time involved. However, there seems to be a time in the Massive Development chart for ISO400 and 1:3 ID11 - that is, twenty minutes, and ID11 is pretty much the same as D76 so you could try that guesstimate.

Hopefully your last few cc's of D76 are not a murky brown colour! Good luck.

It was beautifully clear - I'll give 20mins a go. Thanks for the advice!

Bear in mind I've never tried to push Delta400 except with DDX . . . not advice from me but from some unknown person(s)!!

The MDC suggested 19.5 minutes for ISO 500, so I had that in mind also.

It worked!

Mamiya 6 (folder) with Ilford Delta 400 and D76 (1+3) for 20 minutes.

Thanks again!

D76 is wonderful in that it's quite always 12 minutes @1+1 and 20 minutes @1+3 with whatever film when box value exposed so you can mix conventional grain/T-grain/25/50/100/125/200/400 films in the same tank with no problem 🙂.

Hence my thought about the Agfa APX100 (which requires 17 minutes @1+1) not being an actual ISO 100 film and being one stop pushed when exposed @100 😉
