HI Shawn,
I doubt that the new caps would be the cause of the low volume. Is there a possibility that you may have miswired one of the three caps? Or, that you replaced the cap with a different value?
The 'manual' for the set probably wouldn't have any wiring diagram to go by. The schematic is the best way, and I can understand how you could find it daunting.
In learning how to interpret these, you must compare what you see on the chassis, to what you see on the diagram. Start with the power cord, it is pretty much self explanitory. Other parts can be identified, such as the tubes and the capacitors.
Select one of the caps you replaced. See where it is connected under the chassis. "One end of the cap is connected to pin 4 of the xxxx tube, and the other end goes to a 470,000 resistor....." Then look at your schematic and try to find it there.
You should see the cap connected to the places you saw physically. Do that with the other caps. If you had good volume before, and only replacedd 3 caps, I suspect that one wire was misplaced. If not, then perhaps you moved another wire so that it is touching something? Check to see if the tubes are in their proper sockets.
Don't give up so fast, you may eventually get it. But I'd suggest that you don't replace any other caps until you have verified everything is in the correct place, and tried to get the volume back. Replacing more caps could add to your problems.
Take care,
Gary.
