Hi all
I'm building classic III as a schematic find on a russian site but i'm not sure if this schematic is correct.
No one have a classic III schematic?
Here is my schematic.
Thanks in advant for any suggestion or correction.
MAX,
the device was been back-engineering by our collegue Ivan K. I has did a comparision with Classic I shematic that was been sent at the forum (great thankings!) and it was all OK.
Hi Kt315
The design i post on forum is a my mix from schematic of classic III and I.
I take bf stage from classic I e put same decupling capacitors on power pin of operationals.
For sure in my design there is a my error, i connect r33 on pin 6 of u5 instead on pin5.
I built this device but seem there are same problems on all metal channel , i'm not a electronic engineer but find strange the connession of r1,r6,r57, in this way pin 6 u1b is always at ground.
Other problem is that i cant ground balancing and disc, even in disc mode the device act as in all metal, i presume there is same phase problem.
Bye Max
Thanks
I havent see before yours hint.
Now is clear, as i said at Kt315 i suppose that there was a error in this part of schematic but i was not sure how solve the problem.
Thank a lot
