Minor Vintage Repair?


I've got a 40 year old Toshiba SA-2500  25 wpc receiver I got back in high school. Mid-fi at best in its day but well reviewed in its day and well reviewed recently by vintage audiophiles. It is in good shape and I use it regularly down at my country place. However, the light behind the station indicator is burned out. Without it you can't see which station you're on and you can't tell when the unit is on or off. The clear plastic indicator moves back and forth on a cable moved by the tuning dial. There is a wire that goes to it that presumably provides the power to the light but I do not see anything there that looks like a conventional light bulb.

Anyone have any idea how I can fix this? Probably not worth spending the money on sending it to anyone for professional repair.

Lots of discussions on MAC gear sites replacing the old little bulbs with LED.
I could not find a service manual for free on the net, but there are several paper service manuals for sale on the usual auction sites. It might be a good investment, and if you need more extensive work done it may save bench time if you supply it to your tech.
Good idea.Thanks. I have opened it once when most of the pots were not functioning properly. I used DeOxit solution on the pots and everything works great now except that one light. I won't have time to open it again for a few weeks but I'll look closely at that bulb and see if I can tell what it will take to replace it. The service manual would be handy.
