Has anyone put together a parts list for the quad or studio pre to replace all the caps?
The caps I replaced in the Studio-Pre were:
30uf 500VDC x 3 $9.95 Sprague @ Tube Depot
220uf 63VDC x 2 $ .77 Nichicon @ Mouser
10uf 63VDC x 1 $ .14 Nichicon @ Mouser
1uf 50VDC x 1 $ .33 Nichicon @ Mouser
4700uf 16VDC x 1 $1.75 Nichicon @ Mouser
These are 2010 prices. I ultimately ended up ordering them from Mesa since I was recapping a Simul-Sat and 50/50 and there were a few caps that they only had in stock. It just made sense to order them all from Mesa. The prices were very competative.
The Studio Pre board has traces on both sides and getting a clean solder joint can be difficult at best without pulling the board. Pulling the board means either desoldering all of the periphereal connections or, removing all the chassis components to give the wiring slack to lift the board. There's no easy solution. If you do decide to solder, be aware that the traces can be very intolerant to excessive heat. Too long on the iron can cause them to lift creating a whole new problem.
A good friend advised me that you can cut the old cap out, put one "hook" type loop in the lead on the board side and then lay the new cap down and put the new cap lead thru this hook and form an opposing hook in that lead,crimp them and solder. Then cut the excess from the cap lead. A dab of silicone under the new cap will hold it in place against future road abuse.
It's a good idea to mark the board with a Sharpie or such to note the +/- connections.
