This saga started here: http://www.talkbass.com/forum/showthread.php?t=709001&highlight= Summary: Won a Kern preamp on ebay. The end of the package came apart and the power supply was lost. Someone with this power supply told me the exact description of what is needed: Class 2 transformer 120VAC 60hz 30W Output: 12VAC 1.25amp I ordered this online: http://azsurplus.com/index.php?main_page=product_info&products_id=662&language=en On the site is reads: RH48T-1201250DU AC ADAPTER 12V 1250mA 30W CLASS 2 TRANSFORMER E2 It finally arives after two weeks from Canada and everything is correct EXCEPT it is 12VDC 1.25 amp output not 12VAC Will this work ???? I am not going to plug it in until I know for sure. Also, this particular adaptor is very hard to find. Can I use one that is close? How hard to have the power supply put inside the unit itself as some have done? Thanks for any info !!!
