Sansui Seven question

[KeithD]

Just picked up a Seven. Three of four fuses were blown. Replaced those with 3A, and everything sounded great. Two questions, stereo light and FM light are out. SM calls for 7V 0.16A for the FM indicator, and 6V 0.1A for the Stereo indicator. Do the replacements have to be those exact values? I've got a range of the grain of wheat bulbs on hand, both 8V and 6V, with current ratings of 30, 40, 50, 65, and 70mA.

Also, how do I get these out? I'm not sure how they are mounted in their holders. Are they glued in or are they just a snug fit? I think I'm seeing 4 wires coming out of the Stereo indicator light, is that right?

Take a picture for us if you can, I have done so many lamps on Sansui's I can't remember all the details.
The FM Stereo lamp wants the correct amperage lamp as there is a transistor which turns that lamp on and if it wants to pull too much current it can damage the transistor, and also it might end up being too bright or too dim...
The FM indicator lamp you have some room to move, but bare in mind if you differ from the factory spec the lamp may be brighter or more dim than the others.
I tend to just replace all the lamps in these ageing receivers now....

OK, so SM calls for 7V 0.16A for the FM indicator. Closest I have is 8V in either 0.04, 0.05, or 0.07 A. So, current draw should be much less than spec for any of these replacements. They are all different sizes, so I should be able to just find what fits.

SM calls for 6V 0.1A for the Stereo indicator. I have 6V 0.03 A on hand, so again, I assume the lower current draw is not a problem?

Here are pics of the stereo light area and the FM indicator. Notice there are 4 white wires coming out of the stereo light. Something clearly happened by the FM indicator, though that is the only light out.
