I recently ordered some EQC-V1H224JL capacitors for the tuner board on my 2300. There is a marking on the capacitor of OL6. Doesn't this mean the thing is only rated for 5.5 volts rather than 50 volts? I'm a newby and hesitant to put them in. The other marking is 224 which I think is right for .22 mf.
