Greetings everyone
New to the forum and I have a component question.

I need some assistance identifying some components.
We are rebuilding a piece of equipment the was manufactured in Germany, maybe late 80's early 90's.
There are a pair of what appear to be triac modules.
One made by Brown Boveri and one by IXYS. Both carrying the same part numbers. ( MRR 35-08it8 )
I cannot find a reference on line for the part number on line.
I do not recall seeing the markings before like this with one black and one white triangle in what appears to be the triac symbol.
Any help will be appreciated.

Maybe you could use a newer version. http://www.ixys.com/productportfolio/powerdevices.aspx
Contact them and see what they recommend.

Excellent!
Thank you all very much.
Exactly what I needed.

 

nice old halicrafters, I have restored a few.

 

I do like Hallicrafters radios.
The one in the pic didn't belong to me, although I have had a few over the years.
The last two were S-38's that I fixed up and they went out to other folks.

 

a suguestion for aligning the older radios, use a counter coupled to the local oscilator, it saves the time of retuning a signal generator over and over. also, the highest frequency band on the s38's and some others has the local oscilator inverted, below the tuned frequency, the low bands the lo is above. same for the s40 types.

 

Thanks for the info!
Been a while since I have had one. May pick another one up some time.
