hi folks. i acquired a broken HP 5340A for (relatively) small change. the A28 assembly, p/n 05340-60085, has a couple fried parts on it. anyone have a schematic (and corresponding part list with values)? cheers, -ch p.s. the 10811-60111 OXCO in this unit (option 001) is labeled "upgrade to series 3010." any clue as to what this means?
