Hi,

I want to do some mods on my dbx 160xt

I think the power supply is not very good... +/- 24V is connected unregulated to some transistors at the output stage.. the power supply caps for the regulated +/-15V are far too low...
maybe some of te lf35x opamps could be changed to some better types with more modern specs.
replace the transformer with a potted toroid...
does anyone have the user-manual containing the schematic??

I've found a scanned copy here, but schematic section is unreadable :( http://classes.berklee.edu/mpe/pdf_f.../dbx_160xt.pdf

I hope you can help me...
