Well, if you have 1200$ in your bank I would advise the Duo Audio isolator.

Hi,

Not an expert in this field, I have heard and used a few. I am not a big fan of any ,I stick with old school RLA style x-overs.

I will say that I did like the sound of the Thriev crossover which is the crossover Shorty is working with. It was a clean sounding unit. Waiting for the unit to come out.

nice pic mario -- so do you have both mono and stereo tone controls?
what exactly is going on there.... If you don't mind sharing that is

nice custom face plate -- the 1620MG Ltd.

do you have the chip cradles used for the 1620 phono card mod?

I have some jumpers already -- looking for the chip cradles used on phono card mods -- the one that allows easy changing of the chips from TL084/TL074 etc w/o any soldering after installation...

I think Billy may have gotten some from you a while back...

Regarding the tone controlls

Stereo for house and booth output, the original tone controlls are now used for the three mics

No need for the email,

Do you have a radio shack near you , they have them.

Just be sure you get 14 pin - 7 on each side

I went into the local RS in my dads neighborhood, needed a simple typical value resistor, the saleslady looked like a grandma, I asked her where the resistors were, shes like, Whats a resistor? We have free cell phones today, would you like to have a free cell phone?

the jumper is used to convert phono input back to line level input...
the cradles I was looking for are to swap opamp chips...

Thanks

Hi everyone! I have found the schematics of a 3 way tone control, maybe someone can change it to become an isolator. her's the link:
