I read you are going to build a SSLV 1.1, are you going to compare that shunt reg vs the 1.2R?

P.S. 2k2 in lieu of 1.8K (R11) ?

P.P.S. Happy new Year!

Hi Massimo

I tend to use V12R in all my builds... IMO it is the best (The Optimae was even better "had magic properties" but was too prone to oscilating)

Off course I did not try all options of the SSLV 1.1 so I can not comment.

R11 yes

Like attached pic?

R11 yes

In my humble opinion to don't worry about the best and easy solution is to buy a BiB in the Tea-Bag GB.

Salas, I have five 7.8mA and four 7.7mA K170, could I use?

It will not go too far off I suppose.

Thanks Salas, I will ask Ricardo.
