TR7950

Just found a Kenwood screwup on the tr-7950. On the power-output
board where the PA module is connected is a 470 uf Cap designated
C 1. The silkscreen on the board shows the + terminal going to gnd.
The origional cap that was factory installed was installed with the
positive lead going to the + on the board. This is obviously wrong
as the Gnd Foil is the minus lead not the + lead. The cap had swolen
up and burst due to incorrect installation. Almost blew another cap
till I verified that the MINUS goes to the foil, not the way its
marked on the PC board. 
If you have a 7950 or 7930 you would do well to pull off the back
and inspect the Cap installed at C1. Its the only large filter cap
on this board so its easy to locate. If the case looks bulged, better
get another cap and install it correctly. 73, N5WX @ N5WX.OK
