Tech rates do have a range from reasonable to unbelievable, depending on location. On the coasts that rate is in the 85-125 range I would say and closer to 50 in the least expensive areas of the country.
Then you have to figure the time involved with this recap. It is a long process.
1) repair the unit
2) inventory the caps in the unit
3) determine other items that need to be replaced
4) order the parts, verify in-stock,
5) spend the hours needed to remove the boards swap the parts and reinstall the boards
5a) clean all controls as they become accessible during the disassembly process unless done in the repair phase.
6) bring the unit up to verify work done
7) burn in the work done
8) performance test the unit
9) try to add up all those hours and hours needed to do this recap
10) prepare for the discussion with the owner as to why his recap of more than 100 caps and a few other components costs more than he could buy a unit for off the bay.
A full recap is not cheap. If it is, there is something wrong. This is why we do them ourselves while we plead for cap lists and BOMs while techs don't want to do them.
Guys ask me all the time why I charge around $850 to do a refurb on say, a Pioneer SX-1050, when there are people on ebay offering to do it for $400. I just tell them "one word: quality". Plus all of the above.
