Hi folks! Anybody here has racked some ward beck module with a +/- 24v PSU instead of +/- 25 volts ??
i'm about to rack some m460b and m470a modules, i know they run on +/-25v, but i have acess to a realy good +/- 24v PSU. and to get
+/-25v, i would need to order another power transformer.
Looking at the schematic i see there is some kind of regulation on the board wich drops down the 25v to +/-18v ( +/-21v on the m460b) but on the m470 i see r134 and r137 drops it to +/- 24 volts to feed Q6-Q9 ...
could i use 24 volts instead of 25v? or if i do, should i bypass these 2 resistors and straight feed +/- 24 volts.
Thanks alot for your input, i'm not enough knowledgeable in electronics to be sure about this one.
i attached a schematic, full manual here: http://wbsps.ca/PDFs/Ward-Beck%20Sys...w.WBSps.ca.pdf
