Siemens W293 tuchel wiring

[alexgg]

hi

im wiring up pigtails to tuchels for a siemens W293 i recently acquired

schematic is easily found on kubarth http://audio.kubarth.com/rundfunk/index.cgi

please can someone tell me which pins to wire grounds for in/outs
+ also which pin is for 0v dc

pins 2/3 seem marked for 0v on schematic and also 1 seems marked as ground

I'm a real noob + would appreciate any advise on this

thanks

hi
attached a picture for siemens w295 wiring which looks remarkably similar to w293 schematic on kubarth

can anyone please clarify for me where the output ground goes ?

Output ground goes to input ground. Wire a 24 volt power supply from 0v to +24v. 0v is the negative terminal of the 24 volt supply.
