Motorola model 10128B radio

Post by Bill Cahill on Sat Jan 01, 2011 4:05 am

I got this radio a few months ago from my friend Mr. Detrola, in Michigan.
I looked in Nostalgia Air, and, they do not have even a similar schematic for it.
I have to replace open electrolytics, and, it appears to have a burned resistor feeding B+ to I F tubes.
Can somebody find me a sam's for it?
It's an am-fm table radio. Blonde finnish in masonite, and, wood cabinet.
I also need a good eye tube for it. American no. is 6DA5.

The tube lineup follows:
6X4
6AQ5
6AV6
6BE6
2 6BA6
6AU6
6AL5
6DA5
This looks to be a nice hi fi set, with a woofer, and, tweeter.
Thanks.
Bill Cahill

Bill, I didn't see a listing on the Sams site for that model number. I have some older Sams, and if you can find out what folder it's in, I may have it to scan.

Sorry. Forgot to make the correction. It's 10T28B.
It is in Sams, but, not sure which one.
Thanks.

Can somebody scan the sam's schematic for me? I got radio playing today, but, Eye tube was dead. Found out B+ wire to it got accidentally cut. Don't know which filter to connect it to.

I had already replaced the eye tube.
I got it working, but, had a temporary mechanical short, which did dammage. I'm trying to find out what was dammaged. Maybe the 6AV6. Radio is playing on am, but, not well. FM is basically dead.
