I drove 50 miles to take a chance on a unit that the seller knew needed some work and priced accordingly. It turns out the receiver lived it's entire life just a few blocks from me, where the guy grew up. It was his father's from new and was part of the estate after he passed. His dad was 80 and he said he knew it hadn't been played much in the last 10-15 years. It was pretty dirty and he had to play with the power switch to get it to stay on. It barely pulled in any FM stations but he was out in the boondocks. Pots were scratchy...I tried but he wouldn't come down on the price because he knew what they can be worth.
Well, she cleaned up nicely. I'm not a tech but I blew and brushed it out and gave all the switches and pots the full treatment. Now it comes out of protection like clockwork, about 6 seconds. FM is clear as a bell, tuning and signal meters work, all the indicator lights work. I haven't tried the phono sections yet but there is no bleed through when open sources are selected, in fact she is dead quiet at volume from an open source. I do have some FM bleed through from the monitor switch. Should I worry about this?
About the power switch and lamps. After the first cleaning the power switch was still making bad contact, like the contacts were arcing the lights were flickering. I gave it another cleaning and now it seems fine...for now I figure. Is there a source for a replacement? It's an Alps switch but I can't get a number off it. Also it has a couple of bezel lamps out. As near as I can tell from the schematic there are four 12V 100mA lead type incandescent (I believe) bulbs. About 3/16" in diameter. Will these work from Parts Express?

At 70mA will they be dimmer? I would be OK with the meter lights dimmer but not the edge ones that light up the glass. Since I have to order the parts I went ahead and buttoned it up and took some pics. I'm pretty pleased a visit to a pro will be for a tune up and not necessarily repairs.
Anyway, any advise will be appreciated. Thanks
