Melcor discrete op-amp PCB's.
Posted: Sun Jul 05, 2009 7:18 pmI have 12 Melcor 1731 discrete op-amp boards, as sold some time ago at The Lab. These are bare PCB's, you must source and solder all of the components. Lots of info on building them over there. I have 6 of the Rev. 2 boards, and 6 of the Rev. 1 boards (which have an error, these need a trace cut and jumpered, a 1 minute job). $8.00 a pair including postage in Australia for the Rev.2's, $7.00 a pair inc. for the Rev. 1's. $38.00 inc. for all 12. Tiny boards, about 2 cm x 2 cm for those interested in building a discrete transistor op-amp.
