Not getting a response to the earlier post ( attached below) about a Scott
Stereomaster 2400 I need approach it another way.
I have a fried power transformer ( input winding shorted)
It was center tapped and had two diodes in a full ware configuration being
filtered with a 5000 uf 30 Volt Cap
Also had a winding for a #49 lamp ( 2v)
So the question is what voltage transformer should I replace it
If I drive the 2 volt winding I get 17Volts on the questionable winding
I calculate the 18 volt winding would give me about 25V across the cap
Whereas a 24 volt transformer would give me 33 volts or so
does this analysis seem correct
Thanks
Bob






I recently got a stereo 2400 unit that I was told blew fuses
When I opened it up I found the power transformer primary open and obviously
cooked
I provided dc with an external power supply and it seems to run fine so I'm
in search of a replacement transformer
I'm hoping somebody can tell me the output voltages of the original or even
better have one for sale
The primary DC cap is a 30 V unit so I used 24 VDC on the external supply
there is also a second winding for the lamps
Thanks
Bob
