I'm rebuilding my Space Station power supply... I had gotten all of the parts from my local electronics store... they had matched up the transistors the best they could and I'm curious if two of the transistors they gave me will actually work...
Q3 on the power Supply calls for a SDS202, pnp, or MJE15031... my PS has the 15031.
also Q1 calls for SDS201, NPN, or MJE15030...
I was supplied with an NTE55, will this work in place of the 15031?
I was also supplied with an EGC171, will this work in place of 15030?
Thank you for any help
