In the Thread: The last phonocorrector: “End of Life" Phonostage
Post Subject: It is comming along....Posted by Romy the Cat on: 5/24/2008

Looking at my current 834PT phonocorrector I decide do not convert it into the “End of Life" Phonostage as it is good as it and I would like do not ruin it – I will always take advantages of a good MM phonostage. I took the Expressive Technologies ET-2 transformer and build another small board with 834PT RAAI correction circuitry.  It took 4 hours and I love how I mange to layout everything. It will be incredibly small and it looks that in my new enclosure I will have some extra space.

Now I am thinking about the PS. The old PS I would like to keep with old 2x834PT. This corrector will be not dual mono and I will be using both halfs of the 12AX7. With the incredibly low current that this corrector sucks I think I will not go for dual mono PS . The leading idea not is the following:  the filaments LCRCRC supply and the anode is LCRC +GGRC. The GGRC is a pair of my gas regulating tubes (0A2) that give exactly 300V that the corrector needs.
