Looking for Printol 12 or similar formula

[wildbill]

I've contacted Nacco, who I've been told is out of business. I'm awaiting a reply. I got a list of components from the safety sheet, now I'd like to get the formula. If i can't I'll try mixing Ansco 130.
Ingrediants:
sodium sulfite
potassium carbonate
hydroquinone
1-phenyl-2-pryazolidinone aka Phenidone, right?

If i can't get it, what's closest to Printol 12 or what's that developer most similar to? I really liked the characteristics from long shelf life, long tray life, cheap as hell, and the results on paper.

thanks

Vinny, get some 130. You will love it! The developer lasts forever and gives great tones.

PRINTOL 12 IS A CONCENTRATED LIQUID PHENIDONE/HYDROQUINONE DEVELOPER.

ILFORD CONCENTRATED PQ UNIVERSAL DEVELOPER is my favorite of the type.

Ian Grant posted the Ilford formula on APUG but I can't find it now.

I am also a big fan of Ansco 130 - but you'd need to buy some Glycin (PF).

ID-62 is the Formula Tom's referring to. It's the PQ variant of ID-20 a Standard MQ Print developer.

Ilford ID-62

For Bromide Paper.
Stock Solution
Warm water (125° F or 52 °C) ----------- 750.0 ml
Sodium Sulphite, anhyd ----------------- 50.0 gm
Hydroquinone---------------------------- 12.0 gm
Phenidone------------------------------- 0.5 gm
Sodium Carbonate,anhydrous------------- 60.0 gm
Potassium Bromide------------------------ 2.0 gm
Benzotriazole (1% solution) ---------------20 ml
Water to make -------------------------- 1 litre

To use. Enlarger papers 1:3 with water - Neutral/Blue black tones

With no Benzotriazole and additional Bromide the developer becomes ID-78 which is warm tone

Thanks guys but i'm not giving up yet.

 

[Tom Hoskinson]

Don't give up, mix up a batch of ID-62 and use it.

 

[Ian Grant]

It's worth mentioning that often in liquid concentrates the Carbonate is partially substituted by Sodium or Potassium Hydroxide, this helps solubility and cuts production costs.

ID-62 has been copied by other manufacturers, Forte FD-203 is the same formula but with no Benzotriazole. Using Potassium Carbonate instead of Sodium Carbonate will give a very slight increase in warmth.

Hello wildbill:
Our P20 Print Developer is a very similar formula to Printol 12
