Hello everyone, I'm tray processing RA-4 prints at room temperature. I used Tetenal RA-4 chemicals until I found out that the blix is very problematic because it is sold as a "mono-concentrate" that has too short shelf life. As said here at APUG many times before, you shouldn't use these "mono-concentrate" RA-4 kits, and sadly I've seen this by myself. I was in contact with Tetenal; first they denied the problem but later they admitted it and sent me one kit free of charge saying they would work on with the problem. But I'm not interested in waiting if Tetenal could solve their "problems" or not. I could use Kodak RA-RT developer and blix at room temperature as suggested here, but it would need something around 2 + 2 minutes. Well, that's not so long but one thing I loved in Tetenal RA-4 process was the very short processing time 1 min dev + 15 sec stop + 45 sec blix. It allows so rapid testing of filtering . But all the room temp kits seem to be these "easy" monoconcentrates, ie. defective, faulty products. So, any ideas, is there any decent quick room temp RA-4 kit out there? Or could KODAK RA-RT dev and blix be used in higher concentration to shorten the processing times? Or will it be my destiny to wait for 2-3 minutes longer to see the results ?
