Does anybody have a source for the DV2840S MOSFET or a DV1007 (same
thing, old part number)? Tried Google and Dogpile. Found one place had
them for $30 each. Can anybody find a cross reference to an ECG or NTE
part number? Tried both online, with no results. How about an
equivalent part??

It is for a 2M amplifier project from the RSGB book "VHF UHF Manual"
