Hello All,
Been a while since I have posted on this sight.
I have 70's Magnavox console stereo I am repairing for my nephew. I am no expert at electronics but I can scout my way around on some repairs.
My question is I have a shorted output transistor on this unit. It is a NPN #11N4B, The Sam's schematic shows a Sprague #RT-149, a GE #GE-75, a International Rectifier #TR-26, and a Motorola #HEP-247 as replacements. On the NTE website I could not get any hits on any of these part numbers.
I did happen to find on the internet (Talon Electronics) that a HEP-247 will cross to a NTE130.
I have a 2N3055 which also will cross to a NTE130. Can I use the 2N3055?
When it comes to crossing parts if I can't find it in a cross reference book I am lost.
I have attached the three spec sheets.
Thanks MrModify
Sure miss you KrisBlueNZ
