I'm building an Amp4 that may see some ghettoblaster duty at 12V. The assembly docs say that the relay won't close at under 17V, so I'll have to jumper the relay I think.
If this is the relay:
... can you confirm my understanding?: If I jumper from from C to D, the output circuit is closed, I get sound at the outputs, and the amp works normally.
And -- Do I need to omit any relay driver transistors? I was planning on having them sit there on the board, to be able to drop the relay in later, if wanted.
ps. Here's relay datasheet: http://ecommas.tycoelectronics.com/commerce/DocumentDelivery/DDEController?Action=showdoc&DocId=Data+Sheet%7FRT 2%7FFE1%7Fpdf%7FEnglish%7FENG_DS_RT2_FE1.pdf
