Wondering if someone out there can tell me the secondary current rating of a Stancor 52B046 plate transformer. The secondary voltage is marked near the terminals (2000VCT and 2500VCT) but there is no current rating. This is a pretty hefty transformer, it weighs at least 60lb. My guess would be 400-500mA. I can't find any info on the internet. Hopefully someone can find it listed in an old catalog.

Many thanks,

I doubt you are going to find that transformer in the standard catalogs.

It sounds like an BC-610 transformer as they had approximately those ratings and weighed about 100 lbs.

Perhaps posting a picture of it would help.

52B046 is a Hallicrafters part number.

Yup sounds like a BC610. You need a stiff 120 VAC line to feed it. It will run a 500 watt am rig. I used one for a 4-1000A linear for years then found a second one and hung them either side of a 240VAC line for better voltage regulation. Cap input filter you can get just over 3KV under load.

yep BC 610 transformer. I got a few chokes out of one and  couple of transformers/chokes  for screen supplies and exciter stages.

Hi Ron,
         Go back about 5 pages to a previous post I made about a Stancor transformer and look at the pictures I posted.

Thanks to all who replied. Yes Phil, your pictures show the exact transformer that I have. I am quite familiar with the BC-610, so now I know what this transformer can do. I have two NOS HK-254's. Should be a good power plant for those. probably could run the modulator from the same supply - mebbe 35T's or 811's.
