In checking components I came across these diodes marked:

17
ITT
992

Yep - I've checked the webz - no luck - any ideas how/where to cross-reference these?

What is the radio brand and model number?
You need to give details of what your working with.
Where in the circuit are these?

I have an Idea what they are but I am waiting your reply to verify the functional area.

on mobile so brief - they are rectifier diodes for a two diode full waver rectifier - come from the transformer and go to the multi-section can cap. not identfied on schematic.

Any replacement for a power supply diode or Bridge can be of the following:
Just observe operating voltage and current requirements.

I went to http://www.ecgproducts.com/ and put in ITT992 and it came back with nte116. You can pull up the pdf and check it out. I wonder if they were added later by what you said of them not being on the schematic. If you post what hte model is maybe we can look it up and ring ideas as what it is. I noticed you go by Nashvillerad. Do you ever go to the music city meet?

Excellent - I didn't even think to check the NTE site. What I meant was the designation wasn't called out on the schematic, but the NTE116 analog looks in line as what I would expect for voltages/capacity, etc.

I keep hearing about the Nashville meets - but I've had a lot of windshield time for work these days and haven't been able to keep track of them.

RiF's list is pretty comprehensive.

As a practical matter I only stock 1N4007 and 1N5408.
There's almost no difference in price, and no advantage to stocking the lower-voltage parts.
