PostSubject: Help in Identifying a Blackhawk Radio   2016-05-02, 8:30 am

Hi All,

I am new to collecting radios and recently acquired a wooden table top BlackHawk 259-pl Radio. 
The radio powers on but all I get is static. So I tried to research it on the world wide web and cannot find anything about this radio. 
In fact I only found 1 other Blackhawk radio and it was a 1930's console.

Any help would be appreciated as I would love to get this working again and find out more about this company.

Thx

Are you electronics savy?
If not then you need to read a book on radio repair.
If you don't want to bother, then there are tutorials on you tube to give you an Idea of how to proceed.
test your tubes first.
If you can get static that's a good sign that its working. Does it have noticeable Hum?
If you get static, there are several causes.

The first is called silver migration diseases. That has to do with the trimmers in the I.F. transformers.
The second could be that the Tuning cap has one or more of the plates bent and touching another plate.
Then there are poor solder connections. Also resistors or capacitors that need replacing. You could have a shorted tube.

Hi Cliff,

Thanks for the help I think I can get through it as I do have a background in electronics although I've never worked with tubes. On another note any information on Blackhawk radios when were they manufactured from where did they go out of business generally who were they. thank you

I looked in Beitmans, I had no luck. So I went to radiomuseum.org ther are about four listed under several manufacturers. Philmore being one.
I have a cross reference from Gihardi that listed it Philmore.
I will do some research, but no promises on finding anything.
I also have some other indexes that I will research.
I will provide a link when I can. > Click here!
I saw two styles, both table tops, one a cathedral, the other was a tombstone style.
Which do you have?
Can you post a picture? How many tubes? Does it have a shortwave band?study
Here's a link also on the manufacturer --> Click here!

Here are a few pics. The model is a 259-pl it has a Blackhawk logo on front with an indian chief. Its not as tall as a typical tombstone so I do not know enough to say what type it is. Hopefully you will be able to tell me.

Thx

I don't  see any pictures. A cathedral usually looks like the radio on the top is like the brow on a ship, it's curved and has seam in the middle.

A tombstone is shaped like a headstone narrower on the horizontal than it is on the vertical, and it has a flat top, in other words a rectangular box.

I am going to move this post, because it's not about (Amateur) or Ham Radios.
