Dear George and Allen,Thank you for your answers.
Well, first of all, I apologize, i'am electronician engineer, but my generation just know Operational amplifier, digital circuits and sometimes transistor, but it's quite unusual.
* This amplifier is sell in Belgium under the label "Spark" and is made by "Dared". It costed me 740€(1€=0.9$) The components are not so good (especialy resistors whitch looks like carbons)
* About the input stage, i had also never seen such a so called floating desigm. Maybe the shematic is wrong ??
* About the potentiometer (whitch is on the front panel), it is ideed stupid to put it in the feedback loop.
- One solution would be to remove it and and to put it before the first stage?
- Also an other solution would be to cancel the feedback (is it possible ?) and to lower the gain of the SRPP by lowering R4 (and maybe R2?Regards,
Gauthier
