Chimike Posted March 8, 2022 Share Posted March 8, 2022 Could any technician out there tell me the B+ voltage that the neopak 3.5 power amp operates on. I’ve bought a duff amp ( on purpose , for the case ) but it’s just too well made to break it, simply because the SMPS has blown. HOWEVER , please don’t go poking around inside your own amp, if you aren’t fully trained to do so , very high voltages in there ! thanks, mike Quote Link to comment Share on other sites More sharing options...

agedhorse Posted March 10, 2022 Share Posted March 10, 2022 There are multiple voltages, +/- main rails, +/-15V and +24V Quote Link to comment Share on other sites More sharing options...
Chimike Posted March 10, 2022 Author Share Posted March 10, 2022 Hi , Thanks, Yes, the other voltages are clearly marked on the Pcb’s, it’s the +/- main rail voltage that eludes me. Apologies if I didn’t make that clear in my post. Quote Link to comment Share on other sites More sharing options...

Rich Posted March 11, 2022 Share Posted March 11, 2022 This is brilliant, I didn't know we had a Genz guru in our midst. Now I know who to page if I get problems with either of mine. I have an old Neo-Pak too, it's a great amp. Currently serving as the live room amp at my mate's studio. 1 Quote Link to comment Share on other sites More sharing options...
