Mine has got Obbligato PIO's and they are """" NICE """ Also using a Salas Shunt Reg.
Those things are HUGE! Scared to imagine how much they cost. Did you make much experiment with the input capacitor types?
Ok. Regarding Obbligatos. I like them (thanx to KatieandDad) but I think very worthwhile alternative is my MBGO 2 caps NOS from Russia.
I might reverse back to them after all...
You can use anything you like as long as you can make it fit. Although the Obligattos are HUGE they did fit.
Dont´t know where I should post in this thread with my problem, so I try here.
As soon as I turn the volume down in my B1, also the high frequencies getting damped.
I have to say that in the first place I installed the transsitors wrong with 180 degree. Now I installed them correct but the problem remains

I am using a PCB which I found here

JFETs are symmetrical in construction so should have survived, but thats no guarantee.
Do you have access to an oscilloscope and signal generator to see if you have a bandwidth problem when the signal is attenuated.
